I fully support your opinion and I am sure that the current cryptocurrency market will not follow the 2017 scenario. I repeatedly meet similar statements from your opponent. Many are still expecting a better time to invest, but in fact, they missed this chance back in 2020. So why wait so long to wait for the impossible today. I believe that the current rate of Bitcoin and Ethereum is one of the most profitable.
There's a huge difference from that year to last year and this year. It's already a year for profit for most of those holders that got through a lot of bearish days and it's also a good time for them to keep on holding upon the belief that there's more for bitcoin.
I may agree on what you've said that it's last year and the past years were the chances that they've missed but if they have the same vibes as us and believes on these crypto, they should buy instead of asking if its late or not.
