Bitcoin wallets can be 10 times more safe than Bank accounts. Goverments are known to confiscate money if you don't pay your taxes and banks are also known for bankruptcy in which case you say bye bye to your money. On the other hand you can have a hardware wallet and keep your coins in the safest place

Wrong.
Goverments are known to confiscate money if you don't pay your taxesThen why don't pay taxes?? If you have business it's really a must to pay taxes and that is common in every country.
banks are also known for bankruptcy in which case you say bye bye to your moneyYou think it can be applied as a whole? There are laws associated in every bank so even they experienced bankruptcy you have a good fight and not just a bye bye one unlike when you loss your bitcoin.
On the other hand you can have a hardware wallet and keep your coins in the safest place 
There is no safe place.

(Don't react if you don't get this)
The risk of losing your money is always there, regardless of the currency in which your savings are stored, and the more the bank or purse. The risk is always present. Everyone therefore makes the choice in the direction of better security.
The risk of losing everything in whatever currency you have stuff stored in might always be there, but there is definitely not enough risk to worry about it all the time. A majority of currencies have very minimal risk right now, and something that would be catastrophic to the world economy (like 2008) would more than likely have warning signs if you're paying attention. I recommend watching the movie "The Big Short", which talks about the 2008 financial crisis from an investor's point of view, and a group who saw the signs early.
