Why one project is the biggest risk
The fastest way to lose everything in crypto is to put everything into one project. It has happened, repeatedly, to coins that were in the top ten. In May 2022 Terra's LUNA fell from about $116 to a tiny fraction of a cent in 39 days, taking its algorithmic stablecoin UST with it. In November 2022 the FTX exchange collapsed and its FTT token fell about 94% in 13 days.
UST is worth a note of its own: it was an algorithmic experiment backed by LUNA, not by cash. Fully reserved stablecoins such as USDC work differently — over the whole history on the page, USDC closed within 2% of $1 on 99.85% of days. Its one real wobble came on 11 March 2023, when a bank holding some of its reserves failed and it dipped to about $0.88 during the day before recovering within three days. Even the 'cash' part of crypto carries issuer and banking risk.
Diversification: more coins is not automatically safer
Diversifying means spreading money across different assets so one failure cannot sink you. The catch in crypto is correlation: most coins move together. Since 2021 the average correlation of daily returns between the six coins on the page is about 0.55 — Bitcoin and HBAR about 0.59. In the 2022 crash Bitcoin fell about 76%, HBAR about 89% and Solana about 95%.
So ten coins are not ten times safer. Real diversification also means spreading across asset types — cash, index funds, bonds and other investments — not only across tokens.
Position sizing: how much to put in
The most important decision is not which coin but how much. A useful test: if this went to zero tomorrow, would I be okay? Bitcoin itself has fallen about 83% from peak to bottom (2017–2018) and has had 30 days with drops of 10% or more — the worst about 39% on 12 March 2020. The page lets you set your savings and your crypto share and replays real crashes against your whole portfolio.
A risk ladder: lower risk to long shot
The page sorts coins into four tiers using numbers anyone can check — age, how much trades each day, how violently the price has moved, and the deepest past fall:
- Lower risk (relatively — still high next to normal investments): the oldest, most traded assets, and cash-backed stablecoins as the 'cash' part.
- Mid risk: established large platforms with long histories.
- High risk: smaller or newer projects with bigger swings.
- Long shot: micro-caps, new launches and meme coins — the kind that can multiply, but most of which end near zero.
Tiers sort risk by the past; they cannot see the future. Measured the month before they collapsed, LUNA and FTT both sat in the 'high' tier, not the long-shot one. The example mixes on the page are illustrations, not recommendations.
Dollar-cost averaging vs lump sum
Dollar-cost averaging (DCA) means investing a fixed amount on a schedule instead of all at once. On real Bitcoin prices, $100 a week starting at the November 2021 top grew to about +97%, while the same total put in all at once on that day was up about +29%. Started at the November 2022 bottom instead, all-at-once won by far (about +432% against +73%).
DCA does not beat a lump sum on average; it protects you from the worst timing, which is exactly the timing people tend to choose when they buy at a peak of excitement.
Rebalancing
Rebalancing means resetting your mix back to its targets on a schedule, which forces you to sell some of what has risen and buy some of what has fallen. A $1,000 portfolio split 50/50 between Bitcoin and HBAR from January 2020, rebalanced monthly, ended at about $22,000 against about $10,400 left alone. From the November 2021 top the two ended close together — rebalancing is a discipline, not magic.
Risks that aren't about price
- Leverage: a 10x position is wiped out by a 10% move against you.
- Custody: coins left on an exchange are only as safe as the exchange — 'not your keys, not your coins'.
- Scams and rug pulls: anonymous teams, locked-up liquidity that suddenly isn't, and 'guaranteed returns' are warning signs.
- Taxes: selling, swapping and sometimes spending crypto can be taxable where you live.
A checklist before you invest
- Only invest money you can afford to lose completely.
- Decide your total crypto share before choosing coins.
- Keep most of it in the tiers you understand best; keep long shots small.
- Consider buying on a schedule rather than chasing a spike.
- Avoid leverage, and know where your coins are held.
- Talk to a licensed adviser about your own situation.
Questions people ask
How do I diversify a crypto portfolio?
Spread across several assets and, more importantly, across asset types — crypto moves together, so ten coins are not ten times safer. Decide your total crypto share first, keep speculative coins small, and consider a cash-backed stablecoin or other assets for stability.
How much of my money should I put in crypto?
Only what you could lose completely without it hurting your life. Bitcoin itself has fallen over 80% more than once, and individual coins have gone to zero. For your personal situation, talk to a licensed adviser.
Is DCA better than investing a lump sum?
Not on average — historically a lump sum often ends higher. DCA protects you from terrible timing, such as investing everything at a market top, which is when many beginners buy.
Are all cryptocurrencies correlated?
Largely, yes. Most coins rise and fall together with Bitcoin; on the page the average correlation of daily returns since 2021 is about 0.55. In crashes, correlations tend to rise.
Are stablecoins safe?
Cash-backed stablecoins like USDC have stayed close to $1 almost all the time, but they carry issuer and banking risk — USDC briefly fell to about $0.88 in March 2023. Algorithmic stablecoins like UST can fail completely.
What happened to LUNA and UST?
In May 2022 the algorithmic stablecoin UST lost its $1 peg, and LUNA, which was meant to support it, collapsed from about $116 to almost zero within weeks. It is a textbook case of concentration risk.
What does 'not your keys, not your coins' mean?
If your crypto sits on an exchange, the exchange controls it. If the exchange fails or freezes withdrawals, as FTX did in 2022, you may lose access. Holding your own keys removes that risk but adds the responsibility of keeping them safe.
Why is leverage dangerous in crypto?
Leverage multiplies both gains and losses. At 10x leverage, a 10% move against you wipes out the whole position — and 10% moves happen often in crypto.
