Bitcoin is the oldest and most valuable cryptocurrency, but a crop of nimble competitors, including Ethereum and Bitcoin Cash, could lure investors away.
I invested in a lot of altcoins, and this is the main reason for it. I hope, though I doubt it, to see Bitcoin on the 2nd place.
It's actually really easy to see Ethereum or Ripple on the 1st place, but, I hope, another altcoin, that will come from far behind to take the 1st spot.
I will suggest you for coming back to real world and stop dreaming about things that cannot take place in reality. Too much expectations form altcoins are going to hurt you terribly. Still you have time and chance to withdraw your money from altcoins and invest into bitcoin because in the coming couple of months, it is again going to produce awfully large number of successful bitcoiners, making altcoins following its paths as usual.
