I still hold my altcoins, I do not sell all my altcoins. I will sell some altcoins at a high price and also to buy cheap altcoins to hold. I wait for the altcoin price to reach high, then I resell it. Some of the altcoin I hold are ETH, Crypterium and LTC. My plan is when prices soar, half of the altcoin I will sell and use for business. So I have another income.
