It’s kinda complicated with what you wrote involving bitcoin investment and challenges , no one should view bitcoin investment as a helping hand in times of stranded situation. Even if you made mentioned of back up funds also and no one can predict any situation we face in life so it’s right we always make room for alternative plans, honestly speaking challenges that will cost an investor his/her bitcoin investment is so rare expect the investor never made use of the disposable income when investing rather the investor went ahead to buy and buy without planning, secondly using the backup funds for personal reason without filling back is wrong and it can cost an investor his investment.
