Well I originally had a plan where I was going to save up 4,000.00 USD as "money that I would use to invest in crypto that is also money I can afford to lose". That way I can invest in a big way and it's not the end of the world for me if I fail and lose it all.
I am not you though, but if am to be mathematical and logical about this I would say any money you can afford to loose should not be one that you should be keeping-up in a safe for, and if you think that money when invested in crypto is seen to you as a Big money, then its far-away from what you can afford to loose.
I haven't read to the end but if your title is right then you must have had success in investing, and congratulations on that but, I think for -Newbies- thinking with this they can borrow up money or Empty their saving, it might not go successful and the loss might be depressing, so afford to invest what you won't be let's moneyless if it crashes.
