I got 0.1 bitcoin,where can I invest it?
Invest on a very good Altcoin.
Now is trend for doing a stake, maybe good option for investment, the risk is altcoin easy to dump it's like gamble too, but if you good for altcoin analysis it's not problem anymore.
dont invest to ponzi ,sell your coins and keep your money in your bank account.
Invest in GOLD
