You shouldn't be scared on buying right now actually, you should take it as an opportunity since bitcoin's value hasn't stopped increasing yet. Start buying as much as you can, it maybe a risk but still it might be worth it if bitcoin's value continuosly rise. Bitcoin's downfall is far from happening still I think and we can use the pattern last time it had a bull run to learn when will the next bitcoin's fall occur. For now, we should enjoy the moment and use the high value as an advantage towards our goal on getting rich through crypto.
