There are many ways to start investing in bitcoin because it is not limited to certain groups. Even if we have $ 20 per month, we still have the opportunity to buy regularly for asset growth that will increase slowly if we want. There is no reason for the inability to start except for people who are always looking for justification for their stupidity. Not having a job is their personal fault because many potentials are not utilized to make money.
Regardless of our opinions concerning this matter investing on Bitcoin is a personal decision afterall cause even though you give some people the ideas on how to increase their income so they'll have extra funds for investment since they think they can't go into it with $20 income I bet they'll still find excuse not do it when they’ve got extra income due to procrastination and also lack of patience, those are the major reasons why lots of people haven't involve themselves in it, they'll rather gamble with their spare cash or involve in ponzi schemes to make quick gains, several folks have approached me concerning Bitcoin investment and before you even start explaining you'll get replies like "when would I cash out, is it going to take very long?" Then when you tell them it involves a long-term process and requires patience, you'll see them chicken out of the conversation like they were never interested in the first place, I get that alot and the most annoying part is that same folks would come running back to invest when it starts pumping as if Bitcoin is some shitcoin with short-term profits.
