Questionssssss

Aight So Im starting to take sometime on researching my stuff on cryptocurrency about this For example if I wanted to Invest into some other coin thats unpopular which website should I use? and which "unpopular coin" should I invest in right now? Not talking about BTC OR Eth, and if I did start investing on one What wallet should I use. I am using BITFINEX right now too is that a good site to use?

So you wan't to know why currency is going to shoot up in price? Jump on the train

Go to coinmarketcap and you can see which exchanges trade that particular coin. There is no exchange which trades every single alt coin
