5 best altcoin that have put smile on my face are nano, neblio, gvt, iota and npxs. I am an early adopter of nano as i have it while it's still called xrb, earn quite a lot from the pump and cash out at december. I bought neblio, gvt and pundix at ico, the price was very cheap and i sold my neblio at about $30 each (ico price was less than 1 dollar), gvt at about $28 and i sold pundix when it won the binance voting as the price get pumped very high back then.
