I think the best Altcoin for now is XRP, with a very high volume of transactions this can shift the Ethereum Coins to the second position, and this coin is expected to continue to experience very high price increases, in my opinion now is the time to invest funds we are on this coin because most likely in 2019 this coin will become the best-selling Altcoin in the crypto market, and maybe you will regret if you don't have this coin, the function in banking transactions that makes it selling well in the market is always in the lyrics of world investors. and to shift these coins by other coin coins is very difficult, because the transaksinua volume is so high, the blockchain technology that is adapted, and the banking functions that people really need, make investors buy these coins as their assets.
