It's not just a matter of avoiding a bitcoin pessimist. The issue is that this user who started the topic, has been participating in this forum since August 2010, that is, he already has 13 years of knowledge about the solidity of BTC and about the fundamentals. The user participated in the active era, in the beginnings of every project. And yet this user has the ability to be bearish on BTC. Unbelievable. I don't know what the point of being so pessimistic would be.
Actually, this pessimistic thing is not worth concluding now with him because apart from that user who has been in this forum for a long time, he has also not been active in this forum for a very long time. The last time he was active in this was on February 25 2018 which was the year that Bitcoin experienced a huge price drop after increasing a lot at the end of 2017, so it's only natural that at that time he was pessimistic even though it didn't exist it means to him.
