I've read some advice from Bitcoin experts, they are experts on speculation & predictions about Bitcoin.
Suggestion:
If you want to invest in the crypto world, don't look back and now, look forward, where you yourself never know what will happen, that's the crypto world.

I can draw one conclusion from that suggestion, investing in Bitcoin is not limited to 60% or 100%, as long as you have the will and are able to do it, do it, all that you enjoy.

I'm not saying currently Bitcoin under $20k is the best to invest in, but investing is a good trait. who knows in the next few months it will drop again to $ 15k or who knows in the next few months it will increase to $ 100k which obviously we will never know that, take the history of our ancestors making long-term investments, even though they can't enjoy it, their children or grandchildren do.
