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.
I read your comments saying that it is not proper to say one invested with an amount they can afford to lose but I don’t see anything wrong with that because What i have always known and that’s how it has been taught is that we should always invest with an amount we can afford to lose. It’s all meaning the same but investing an amount you can afford to lose sounds easy for beginners to understand more and if investing lower amounts is what is convenient for an investor then he should proceed with it if he is adopting a DCA strategy gradually he would accumulate more bitcoin. Even with enough discretionary amount an investor should invest with the most convenient amount he is capable of.
Although long-term Bitcoin investments are generally considered lower-risk and less likely to result in financial loss, it's still wise to invest only what you can afford to lose. This cautious approach helps avoid dipping into funds allocated for other purposes, even if you don't expect to need them for a while.
