I am not trying to discourage you from investing in bitcoin, but with the responsibility in your hand and your financial status, it seems you are not yet ready to invest in bitcoin, and if you try to force yourself to invest in bitcoin, you are likely to sell your bitcoin investment along your accumulation journey to survive because your family depends on you to survive. Just focus on how you will figure out how to get a good-paying job first, so that it will allow you to take care of your family's daily expenses at all times and also give you a good discretionary income at the end, which will allow you to invest in bitcoin without finding it hard to do.
even though from the explanation he has given, his finance doesn't look to strong but since he is making a saving which he hopes he will be able to continue doing for two years before starting off his bitcoin investment, if I am in his situation, i would rather start investing with the money he is saving while increasing my hustle so before the end of the two year plan he has, i should have gathered some bitcoin and before then, i should have boosted my knowledge and it will be easier for him to continue investing for the long term from that time.
truth is that you can't be too ready to start investing in bitcoin if you keep giving excuses of how financially handicapped you are. very few persons where very comfortable financially before venturing into investing. fortunate enough for bitcoin, it doesn't require you to come in with a big shot at a time, with the DCA method, the amount he has allocated for his routine saving can end up being used for purchasing bitcoin as long as he has the knowledge and opportunity to start investing.
but at the end, it's best for everyone to make his decision based on the peculiarity of his situation and if his finance is not enough to start investing and the responsibility he has on his shoulder is quite much that he can't manage investing and sorting out those responsibility, then it will be better to set the right foundation in place before considering a start in his bitcoin investment. investing ion bitcoin is not a must but if you are someone that truly wants to key in and not regret having the opportunity of investing in bitcoin at these prices in the future when bitcoin might look too expensive to come in, then its best to start even if it is with a very little amount and work out on increasing your accumulation amount with time.
