It’s completely wrong to think that someone has to change their mind just because Bitcoin is worth $60 000 today, and 8 years ago it was worth a few hundred dollars. It’s not a matter of price or blockchain, such people will always find a reason to have a negative opinion - some people are just like that and will never change their mind.
I personally know people who consider Bitcoin a scam which will fail sooner or later, they thought so 5 years ago, and they think so today - and when they ask me what’s going on with BTC, I tell them it really failed - time is too precious to we spend it on such people. The only difference that may exist then and now may be in their subconscious, before they really believed it was a scam, today they don't really believe it anymore, but they try to keep the idea alive - it's easier than admitting that they were wrong.
After all, how many of these nocoiners are paid to shill the existing financial system?
Yes, it's 8 years ago and no wonder people thought that way actually, and things changed already, people grow up and might learn new things, so i guess no need to hate or look down on someone's opinion from 8 years ago. Maybe that time, earning and selling btc is the best way, they have no idea it will be this high so they don't really believe in the concept of holding, who knows right?
