I think that buying Bitcoin is also a wise decision. You didn't get profit from Cardano now, but I am sure that if you are patient enough, you will hold Bitcoin for a while and you will also get a good profit. Moreover you are so young and already involved in crypto, so you have enough time to make money on this market, so just take your time and don't give up.
Indeed. If your holding Bitcoin or other coins that possibly give high profit then no need for you to be sad since you will surely earn your profit with that coin. Choosing other coins is a wise decision especially when you choose Bitcoin. Maybe Cardano will not give you profit but I'm pretty sure holding bitcoin for a while will give you a good profit in the future. Indeed. As long as they are young and can make income in other way, then there's no need for them to be sad because they have a lot of time to earn money, if they just give all their effort and be patient always then they can earn and learn especially to all of those mistakes they've done.
