Also the single fact that institutional investors (american funds) not long ago started trading with the Bitcoint points out that the marketcap will double, triple and quadriple in the course of 1 year or so. IOTA needs to get on the good side of FCC by implementing better security in near future.
I didn’t mean only IOTA has the chance to take over bitcoin’s #1 spot. I meant any coins have the chance based on today’s trend as long as they do it right. I don’t think it will take a decade. Again, based on today’s trend it could happen in a couple of years.
IOTA is different from this prospective, the number of transactions per second is unlimited. As long as other factors are covered (such as security holes, trust by users to dev team, bug fixes with the second transaction erasing first unconfirmed transaction, etc) this coin has a bright future. But there is also possibility that developers won’t improve it and some other better coin with frequent transaction scalability comes out and IOTA will loose momentum as the result.
not all blockchains have that weakness, only those forked from BTC. Take a look at the sky coin whitepaper. In theory it should be able to scale. Not tested though.
