I'm quite confident too that in 5 years from now 10 000$ worth of crypto can lead to a million. However, the hardest part will be fluctuation.
Ex: Next boom value go up to 100 000$, then drop to 40 000$ --->>Panic will get many sell here.
Inside on 5 years i dont think so that we would able to reach such heights and its really high too consider and not realistic at all but possibilities are always there since we wont really know on what would be the potential price of bitcoin on upcoming years to come to us. We would really able to witness its progress as the time goes by and hopefully it would progress even more and we would able to see those numbers.
