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.
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.
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!
Losing life savings in bitcoin would literally hurt you everyday, but its up to you on how you manage your bitcoin. Thats why they always say investing in bitcoin would be risky. It depends on you if you are willing to invest or not. You need to have right and enough knowledge so you can hadle different bad scenarios in bitcoin.
