Investing what you can afford to lose means that money which you can dash out, that money which you can use for ice-cream, that money which you can use for shawama, that money whish you can use for drinking without having any effect on your pocket or any other of your expenses or having effect on your emergency and reserve fund, when you bring out such little amount of money for investment you don't feel the impact at all, using DCA strategy to accumulate for long-term of 4-10 years now makes it more easier and valuable for you, but along the years of investment and you happen to lose it, it will not be heartbroken compared to investing what you cannot afford to lose that is investing a huge amount of money.
You need to understand that financial capability differs individually and so it does too differs when considering what should be seen as money we can afford to lose, the amount of money that you will consider as money you can afford to lose will be different from that of others and bitcon investment is made in such a way people can come in within their own financial capability based on their discretionary income, maybe if your own will be the size of ice cream money others may not be the same and that is the reality.
Of course, each person's income will be different and also their expenses will definitely be different. But I understand what is meant, it's easy to enter whatever money we have, of course after we meet our living needs and other needs. Whether it's big or small, it doesn't matter. Because if we wait until we have a lot of money, then how long will we wait? Most people who end up not investing at all are people who delay until they have a lot of money, even though with a small amount of money they can actually do it. This is the same as someone who prefers to be unemployed, even though there is work that can be done, only the salary is not as expected.
