Yes im sure that there a high potential of become successful in holdinh cryptocurrencies. Imagine that you are just waiting and in the end your money profits a little by little. Then someday in the future you will be in a red hot lambo. They would plotting what you got.
I agree that holding cryptocurrencies for a long time will make us become successful but it depends on how strong we can hold the coin because not all people can do this. they really need to wait for a long time without know when it's over and they need to have other works and not just doing trading only. I think if we can be patient and hold the coin and we still trying to earn more coin in other jobs, we can really make a lot of money profits in the future.
