I just saw this thread and also makes me wonder why does the title is too far from the content of the post.
The OP has been banned, so anything suggested for him is only likely to become useful if he actually still reads it.
I strongly disagree to judge people who just sold their bitcoin, For sure they have their own reasons why they sold it and has the freedom to sell it. It's their own freewill and for sure there are regrets to themselves too.
Bitcoin has real use cases as means of payment, so not everyone is going to hold on their bitcoin as a long-term investment because some of them spend it on buying things. So of course it's true, sell now or later, spend now or never is the full right for whoever they are, your bitcoin is your bank.
