You should buy BTC or ETH at this time and sell some time later, that would be better. Currently, ETH and BTC are still very attractive.
I agree, btc and ethereum are best, price are very competitive in the exchange. OP must add ethereum in the list these are the top choice of most users. I am sure on ethereum could give a huge profit in the future.
I don't want to baghold it for long.A few months is the maximum i want to hold and buying BTC at ATH is not a smart move at all.Eth also rallied from 300 to 490 and i won't buy it also just to hold,maybe to trade it for other alts.
So i still look for 2-3 alts to buy but can't decide which ones.Will keep researching
