By this very sentence I can see that you aren't a large investor, nor a bitcoin maxi. Nothing wrong about it, but it shouldn't be your first rodeo.
Were you scared when we fell at the start of the covid pandemic? Were you scared when Roger Ver proclaimed BCH the new king?
I don't think these are "bitcoin's problems". Every network and any computer system can be attacked. Every network can suffer a DOS attack, but each attack tests the network and makes it stronger, just as every attack cost the attacker money. If someone is willing to pay $1k (yes there was 1k USD fee paid in the last few days!) to send a transaction, let them! Bitcoin wasn't design to forbid that.
