Learn everything from within, that's the first options that you should do before buying bitcoin as your investments for the future. If you do absorb all the characters that a cryptocurrency is having, then you can decide whether you're going to buy or not. For now the trend of bitcoin was doing great and positive so it's up to you to decide all by yourself. We can't force everybody to buy without proper understanding.
I suggest to start while there's an opportunity before second ATH comes which is much higher than previous one.
In general, he must be strong enough and that only can be acquired if he is totally ready to face the consequences otherwise, better not to try. So many people have blindly invested in Bitcoin and have no surprise they just lose. And I hope this could not be going to happen with OP and neither to force him if he is not sure about crypto.
