I quite relate with what the op is saying, but sincerely, I don't usually want to believe in this things cus they have their negative sides, for example , if you believe in some thing that has not happened to you yet, you are likely to attract such thing to yourself be it good or bad.
So about the jinx thing and crypto, this things happen to me too, I sometimes buy into a coin, after buying, the coin starts going down, but few hours after I've sold it, it start going up leaving me to think that some spirits don't want me to make money in crypto, but I just consider all this as nothing but Ill luck at that moment, I know and believe I don't have any bad spirit following me.
