With all due respect, in retrospect I don't think you should consider "I had 0 (zero) issues" as a condition to put all your life savings or deduce something is bug free. If you are not risk adverse, putting 1/4 would have been better. Just one example: many people use bash and yet there was a critical bug discovered in it in 2015 I think, heartbleed. And yet it was considered safe to use for years.
