To be serious about this, nobody expected Luna to be a pump and dump coin. I hope people should be wiser by this time not to invest on altcoins unless they see it as gambling and be treated as gambling.
This should be a great example that no crypto except bitcoin is safe. If anyone really wants to be in crypto then be in bitcoin, as simple as it is. Just imagine this, if there were no bitcoin then would there be any crypto. No. So why play with fake digits when you have the real one for you. It's not that you have to have a whole bitcoin.
You want to buy $10 worth of crypto? Buy bitcoin.
