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!
If what you say is true then it's crazy. Bitcoin prices may fall deeper but I think about $ 100 is not possible. A lot of people are waiting for bitcoin about $ 5000 to buy and if it's about this price it will be rising back and probably will not go down again. This market is still very popular and I believe it will thrive.
