to long term investing then that would be great or at least in the next Halving in which will take place in the last quarter of 2024
show your willingness and sure there will be better coming your way. 9k profit is so cheap if your brother will be wise enough to
keep that bitcoin inside her wallet for the whole year from now and with that he will be multiple richer at least that would last him
more than a year or at least 2 years before tasting that product.
But even if OP is lucky or they both hold onto bitcoin until it hits a new ATH during the next bull season, that still won't help them build a career by investing in bitcoin. Invest in bitcoin with a capital of 30k$ and do you think bitcoin will make you rich and successful even if bitcoin reaches 100k$? If we could easily build a career just by investing 30 thousand dollars in bitcoin, I think people wouldn't have to struggle for years to go to school, struggle to find a job, open a business...to build a career. Bitcoin can only help us improve the economy and help us increase capital to do many other things, it cannot help us build a career just by investing in it.
