"Cryptocurrency was an opportunity; those who seized it a few years ago made good profits, while those who couldn't have now missed out."

This is an opinion and it may be true, but I disagree. For most cryptocurrencies, a eulogy can be read, perhaps, but I don't think the same for cryptocurrencies that are accepted by institutions or invested in by large investment firms.

Yes, cryptocurrencies had risen so much in the past due to significant interest, and it is difficult to capture that interest now, which is why there will not be another rise like before. For this reason, I find it reasonable to be cautious at this time and to focus on coins that investment firms are directing towards and that are accepted by institutions.
