- There's only one thing you can do, op, this is the only way to do it, when you have money, immediately reduce the money you allocate for bitcoin, as long as it doesn't affect your daily expenses, just do it. Just don't do it that when you have money, you will buy everything with bitcoin and then you will go hungry and you won't be able to pay what you have to pay.
As long as you don't have anything else to do but be long-term if you don't want any hassle, just hold on while you save up bitcoin. Now if you don't have anything to buy, just wait again until you have a new opportunity to make money so you can buy Bitcoin again. That's it, you will save up again for sure in the end.
