The above, and
-You can withdraw your crypto into cold storage away from control of third parties and governments, or transfer it to someone else, or purchase something with it.
-But if you do the above or trade on an overseas crypto exchange you have the risk of total loss from a mistake or a hacker.
-Crypto cannot suddenly dillute shares or reverse split. You have a guaranteed share structure.
-Far less news and more ability to apply pure technical analysis to trades.
-Generally more volatility in crypto plays. Crypto gives you the strength of a mid cap stock with the volatility of a penny stock. Most stocks you invest hoping to get 500% over 20 years. In a well timed crypto play you can hope to get that 500% over 20 weeks or even 20 days. (In some altcoins ive seen it in 20 hours)
-Somewhat more fraud in crypto. Lots of overseas encrypted fraud, shady exchanges, and little action from authorities to hold those accountable.
-Decentralized exchange markets you can attempt to arbitrage.
