Bitcoin and Ethereum are the best coins today that have been able to last a long time and are very good for us to make as long-term investments. and both of these coins have been able to prove that from the very beginning of the launch, they are still surviving and are in great demand. but in my opinion there are some good coins for us to hold for a long time such as Litecoin and Dashcoin because they also have good prices and enthusiasts in various cryptocurency markets.
