Bitcoin helps to make money, but he does not reduce the number of unemployed. It is not even the currency you need to earn now, but the investment that secured people can afford.
You have a point, on some aspects though it did help the person earn from investments but those who are poor and needy still lives the same. It did not help them because they need to be trained like most that I have known, my friends and the people around even have a hard time understanding bitcoins. But for some as yiu said it did help them. One thing wonderful about bitcoin is that it could help the community since money can be distributed across nations. It is like you are working like overseas working for oneself and the country by doing it online.
