In my opinion, the two Altcoins can be potential and high price increases in the near future is ETH and Ripple.Because they just wait for Bitcoin to return, the ability to multiply 3 or 4 times is possible.
I wonder how you do your speculation before concluding that the two coins you mentioned will does increase in the near future. Dont get me wrong ETH does have the potentials as you mentioned but for Ripple, I dont think so because pump in price of the coins is false and I believe you make the Ripple base on the false price movement happened through manipulation.
The two great coins of all time will always be
BTC and ETH.
Hi friend... I agree with you, and it is certain that the most potential coins are BTC and ETH because these two coins have been tested and are most popular among people, while many other coins are good and grow faster, but security and stability have not been tested like BTC and ETH in my opinion.
