Search for a feasible investment, do not go full YOLO on gambling. Try researching thoroughly first before putting all your bitcoins into a single investment so that you will reduce the risk of you getting burned in the end, plus do some other stuff for other people that might find your seevices useful to them, among other things.
Lastly, don't make decisions solely on your emotion or mood because most of the time, it ruins your strategy and also your bankroll.
That is a wise advice. Never use all your money to make one only investiment.
If you split your money into some good investiments, you can be more safe, and the profit can be the same. Unfortunelly, I don't know good investiments to split your money... I see a lot of fraudulent investiment sites and don't know the good to invest.
I just know about lend money on exchange, but doesn't look good, because we can receive the payment in alt-coins, maybe.
