Indeed, it doesn't feel easy when you look at the price of BTC because the price continues to rise, but what is certain is that because I put in money that I was ready to lose, which was put into buying BTC, of course it felt very light and definitely without a burden.
I prefer you say investing with a discretionary amount because saying that you invest with an amount you can afford to lose seems to me that you are undecided about the productivity of the asset you are investing on thereby you can reluctantly invest lower amounts in your DCA even if you have enough discretionary amount to boost your investment. Investing with an amount you can afford to lose do not necessarily mean that you should have that mentality that it can be lost especially if you have a long term mindset. It is mostly those with short term plan that worries more about the amount they invested with, even though it is an amount they can afford to lose without having a deep feeling of emotions if actually such scenario turns up in the future. Bitcoin has gone above those days when most people were investing in it with fear of it crashing along the line. However, it is not a prerequisite that you will make profits at every point in your investment in bitcoin but there is need to have that positive mindset while investing at the level of your discretionary income.
If I may ask, where do you think the money an investor can not afford to lose is or will come from? off course any money an investor will say he or she wants to use for investment and they can afford to lose it, is from there discretionary or reserve funds unless the investor doesn't understand... So he or she is not wrong by saying investing what we can afford to loss and you could not tell for sure what mentality he or she has about the statement and as a matter of fact he or she didn't emphasize on it to the point one will think he or she will be investing in Bitcoin reluctantly. Even though I will love to say that some people have a better knowledge and understanding of Bitcoin investment I will also want to tell you that there are people who is investing in Bitcoin with fear even till tomorrow, have you ask yourself why is some rich folk investing below what they are suppose to...
