Should I sell my BTC or wait till it goes up and why do you think it will go up?
Well if you want just to get more money using bitcoins, then you shouldn't sell when price is low, because you will lose your money, sell only when they're expencice, and yes price will rise now so you should keep them
Yeah selling at current price wont be profitable enough as the price is not too high at a moment so if you hold at a moment and sell at the time of halving can give you higher profits.
