yes i think that people are free to invest with any amount of discretionary income they have at their disposal, as far as that amount is coming from individuals discretionary income then there shouldnt be too much of a problem. because in bitcoin investment sometimes even when people are dcaing little by little and probably a particular week or month an extra or additional money comes to them and they finished sorting out their basic expenses they can decide to buy a lump sum with that additional cash that comes in for them either as a result of bonus they receive from work, or they win money from lottery or other sources. so its legal to invest with a good amount of cash as far as it is your discretionary income.
People have a choice of investing whatever they want to invest from their discretionary income, and that makes everything balanced because it is a personal choice that is made nd you don't have to bother with what they do with their discretionary income. It is not as if they are spending it on themselves, but rather they are investing, which is one of the best ways that money can be used, you are securing the future.
And when they continue to take this idea seriously about their investment, because that is the only way they make things go forward for them, because from the look of things, when it comes to investment, people are always losing ideas, and this is why they need to have knowledge, and from there, options are made available.
From the beginning, I have been a preacher of investing because I have seen a lot of potential in this situation, and that is why I encourage people in the little way you can encourage people. I do it because it is always a good opportunity to invest in Bitcoin.
