Overall, when comparing Bitcoin to other inventions, considering the limited resources Satoshi and the early developers had, I view it as one of the most successful inventions security-wise. Moreover, as the market grows, Bitcoin's strength will increase, which will enhance the security of tools related to it.
For now, please stop conflating user or code vulnerabilities with Bitcoin itself. I would argue that even in that aspect, Bitcoin is still far more secure than the traditional banking system, especially since a wide range of users are tech-savvy. Credit cards, which have been around since the 1950s, have had 74 years to evolve, yet people still expose their credit card information to hackers and scammers. Bitcoin has hardly been around for 15 years.
It's the flaws of people, not BTC's basically.
Thus, a person who goes into space should know what - can - happen to him.
And, to be fair - people do send money, including BTC, to hackers - it doesn't change the fact that the BTC is still secure in itself
