People buy lottery ticket all the time, thats total fine, spending $5 here and there for fun. But if you mortgage your house to buy lottery tickets you are crazy.
Apples and oranges. Every investment is risky but you can't compare lottery ticket to bitcoin.
Same thing with bitcoin. Spend a few grand for chuckle is fine, chances are you wont see your money again. Heck I would pick up a few bitcoins too when it drops below $100.
You will spend your whole life waiting for that and that is not possible scenario unless dev's seriously mess something.
If you spent your life savings buy Bitcoin, get out now while you still have something left! New crypto currencies are coming to replace BTC. Stop torment yourself everyday watching your money goes into red day after day after weeks after months.... you will spend your retirement working at McDonalds trying to earn it back!
Investors have right to do anything they want with their money.
