Which Altcoins you believe can go to the mainstream market in the comming years?

Bitcoin is in the process. But what other altcoin can make the most out of the craze in the market which Bitcoin has created. I think that it will take few more years for the other cryptocurrency to become a mainstream currency. And it will remain to be a financial asset for time being. XRP and WTC may come out the earliest to the market with the things going around them.
