Exactly, slow and steady is more important than trying to rush your investment to have big portfolio and this is what some folks do, they think going beyond there discretionary to invest in Bitcoin is the best way to go about it but it is absolutely the wrong way because our discretionary has to be used wisely and again some do this because they feel this investment is a competition, some are investing just to have more Bitcoin than there friends and..., not knowing or considering the fact that people has different source of income and people also have different capacity, what I can afford to invest in Bitcoin may not be what the next person can afford to invest because of our financial strength but some folks always don't consider this and soon they will be running and jumping, panicking because of ignorant.
Anyone investing in bitcoin using beyond his discretionary income is only gambling and will end up selling his bitcoin investment, if the price is below his entry point at that moment, he will run at loss. This is why we need to use only the amount of money that we can afford to use to keep our bitcoin accumulation ongoing from our discretionary income.
Life is not all about competition, neither is bitcoin investment too. If you are receiving the same income with your friend and want to be in competition with him on bitcoin accumulation, you might get it wrong because your expenses and his expenses wouldn't be the same, he might have less expenses than you do. Keeping up to consistency and ongoing accumulation without selling a dime is what matters a lot.
