But saying that we should invest with an amount you can afford to lose makes it looks as if we are gambling or we are trading, this is an investment, no Investor will be happy losing his hard earned money, so in my own opinion, the right statement for such phrase is invest with an amount you can do away with for a very long period of time.
You are making the statement very complicated. Losing money does not mean that you are going to lose the money or that you will easily lose it. You can take this word to mean money that you will never need to meet your daily needs or meet basic needs.
A lot of people has ues that word in place of
investing the amount you can afford but however for the clarity sake and diverse understanding from people some person could be thinking on the Statement that the poster meant that something could happen on the money, without knowing that may not be what he meant, because that's what you were thinking @Barikui1 meant on his post, so however for the confident of the newbies why not just the money you can afford, so that they will not get the wrong picture of the conversation. So in addition to what you have contributed @Jewan420 Bitcoin doesn't swallow money because those terminology is for someone to no that there might be upcoming activities that you don't need to get broke, so the money you will be transferring to Bitcoin shouldn't have importance to any of such activities in terms of wishing you could have not use such amounts.
