When you put money gradually into Bitcoin, you should remember that the price can change drastically, making it invisible that you've put some money into BTC last time or compensating if you don't put it in. It might not pay off, that's the problem. It's always a risk, and investing each month is a pretty significant commitment and requires a lot of trust in BTC. Also, people are often putting some money into savings, intending to use some of this money within a year or two, and with Bitcoin it might turn out that the money isn't there when the person needs it because the bear market can last for years.
