Well technically, it is not because of crypto, it is because of your interest in learning more about it. I think it is very natural for anyone to be interested on it and it is really tempting but as you have mentioned you have already learned your lesson, good for your you were given a chance to still have a stable job. No matter how great Bitcoin is, nothing should just make you do things with out further thinking about it first, do not let go of something that has proven value just because of a new thing that may have a potential, always be on the safe side especially if you are the one providing for your family, be wise and smart on every actions you take, it will affect the entire family not just yours.
