Right now, bitcoin seems to be booming and cashing out from it for an alt could be a hit or miss, while bitcoin could keep rising in price. I'd say that there's no such thing as "best coin", but really it's all just talk. People say that ICOs is where it's at, but while some seek quick profit there, this is also something seeming like a bubble and not too sustainable.
It takes some risks if you go for the "hit or miss" kinds of coin. Your investment will be like a do or die thing. Because there is really no best coin if we try to analyze everything. All their prices will go down and then up and then down again. That is the ride for every coin. Your role is to find the right timing. BTC is different though, most of the time.
