I suggest you invest a portion of it to a reputable site and save the rest or keep it and wait till the right time when the price reach it's peak and it'll give you high return. In every investment/trading never set aside the possibility of losses. be ready to take the risk just in case so you wont get depressed in the end.
That's the usual strategy of bitcoin investors. The best thing to do with your bitcoins is to buy some cheap but potential cryptos, wait until the price increased at least 10-15% and sell. Everything has its own risk so don't forget about it, you'll lose everything if you don't get cautious.
