so I can still work part-time in bitcoin without exiting the real job
The question there is why quitting job and riskinG your future on bitcoin? I think this is not a good idea for quiting job so that you can do full time in bitcoin And it is just like suicide whaT if the price drop well you lose for that and you turning yourself a homeless and helpless person if the time bitcoin will fail.
I think the very best for threating bitcoin is just for savings only.
And full time on bitcoin can only be applied by those person who really doesn't have any chance to get work like a disable one or smaller job rate in country. You must have a fixed earnings here and bitcon won't give you that since you care for it's price to make profit. Life needs everyday support and not by comparing it to a price volatility in bitcoin.
