Honestly it will be hard for any alt to top the top two, not even ledu in a short term.
it is difficult to imagine any altcoin in second place except Rippl and ETH. I think that they will still be fighting for 2 place
I hope very much I will stand for the first place, and not for the second. Even before a certain period, Bitcoin will be relevant and will bring a good profit to investors, but over the years, its relevance will decrease.
