Risk: How Much Can You Afford to Lose?
If you can only afford to lose 20% of your savings, your max Bitcoin allocation is $3,000. The remaining $12,000 stays safe in the bank.
This 80/20 split would be worth $38K in 5 years (Power Law) — capturing Bitcoin upside while limiting downside.
DCA Entry Strategy
Instead of buying $15K of Bitcoin at once, spread it over 6 months at $2,500/month. This reduces the risk of buying at a local peak.
Should You Put $15K in Bitcoin?
The bank is guaranteed but slow — 4.5% APY barely keeps up with inflation. Bitcoin is volatile but has dramatically outperformed over any 4+ year period in its history. The answer depends on your time horizon and risk tolerance.
Not financial advice. Bitcoin can lose 50%+ in a single year.

Frequently Asked Questions
At a 4.5% bank APY, $15K becomes $19K in 5 years. In Bitcoin under the Power Law model, the same amount could reach $117K. However, Bitcoin's worst-case scenario (60% crash + recovery) projects $47K. An 80/20 bank/Bitcoin split projects $38K — a balanced approach.
Bitcoin Gate projects $15K in Bitcoin could be worth $117K after 5 years under the Power Law model, or $37K under the conservative 20% CAGR model. For comparison, a bank account at 4.5% APY would yield $19K over the same period.
Instead of buying $15K of Bitcoin at once, consider dollar-cost averaging over 6 months at $2,500/month. This reduces timing risk. If you can only afford to lose 20%, put $3,000 in Bitcoin and keep $12,000 in the bank. This 80/20 split projects $38K in 5 years.
Bitcoin's worst historical drawdown was approximately -80%. If $15K drops 60% in year one but recovers along the Power Law trajectory, it could still reach $47K after 5 years. Over 10 years, Bitcoin has never had a negative return from any starting point. The key is having a time horizon of 4+ years and not needing the money during a drawdown.
