there are too many altcoins that will give you profits in the short term. for example, you can buy waves, iota, kmd, ethereum, monero, litecoin and another cheap coin. I can say like this because almost altcoin gives a sign to increase because bitcoin is already in the bottom so you choose any coin in the market. but you need to analyze by your own because not all suggestion that comes to you will give a good result in next weeks.
