there will be noone can overtake the Bitcoin place in people mind,
because people only understand about Bitcoin and most of them labelled it as a cryptocurrency itself.
which mean even though IOTA has a lot of tech and development compared to Bitcoin,
people will only understand about Bitcoin nothing more than it.
Exactly, although Ethereum is much better than bitcoin, people still think Bitcoin is the sample of crypto currency, so altcoins have no chance to beat bitcoin.
