bitcoin is built with a strong foundation and system comes with strong security so it is not easy for a thief to take over, the current weakness in bitcoin as possible about legality
Even Hacker is difficult to attack bitcoin network, becasue It does not has data center. so We do not uave to worry about bitcoin has strong security.
I think you're wrong because if the hackers cannot hack any related to bitcoin then what are the past incidents that happened? Like the blockchain has been hacked a thousands of bitcoin just got stole but the hacker give it back and also the hacked exchangers got hacked last year and stole a lot of bitcoins also. There is no safe in internet and anything can be bypass and hacked even bitcoin.
That's why bitcoin is very risky but still people are trusting it, we learn from experience and we are getting ready for possible hacks. This days, the hacking incidents has been lessened and that means the crypto currency community are getting stronger, one of the reason is that we are surrounded with smart people both (good and bad) but majority are good people and they will protect the interest of bitcoin because they are also making money on it.
