In the future, you could invest in cryptocurrencies under the ISO 20022 standards, a future of 5 to 10 years, those will be worth a lot

Hello, good morning/afternoon or evening depending on the time it is in your country; I am new to this regarding cryptocurrencies.. and I invested 50 dollars, any recommendations or advice from your side? I invested in these coins, which do you recommend selling or buying??? I would greatly appreciate it from those who have been in this cryptocurrency thing for a while and also from those who are just starting like me.
