I think the best cryptocurrency is only 2 types of coins, namely bitcoin and ethereum. Both coins are like the mother of other coins, I only invest in the two coins, because the coin has a clear and definite future than the other coins.
I also agree to the choice of the best coins at this time indeed only on these two coins that have guaranteed their growth again and will continue to survive in the future.
investing in bitcoin and ethereum is currently a pretty good opportunity to buy, because these two coins have experienced a fairly deep price slump and we can get a lot of money to invest at low prices.
