I have about 3.9 btc saved up and a couple more in different altcoins. And your plan of taking about 25% from each paycheck and converting it to bitcoin is a pretty nice idea and I have also thought about in the past and tried to implement it but it only worked for a few months and in case of emergency I had to use those funds which I saved for investment in crypto. But I will also be doing the same by saving my money and investing it in crypto.
