I was reading the last pages of the thread, and i want to make a mention.
When everybody talks about 100usd per week into investing in BTC, that its quite good and sustainable for first level countries, but in low income countries sadly if you dont catch the BTC in their very very early stages is difficult right now to accumulated some decent quantity.
Also in second level countries like Brazil it can be so much money for the regular person. The other problem in very low countries was, in the very eraly stages of btc like 2010 until 2015 it was difficult also to buy BTC, because in some cases people doesnt have internet or even where to buy, and in a lot of countries the acces to foreign currency is difficult.
Now that problems still exist b ut the market is much bigger than before and you have the opportunity to buy more easily, but now you cant buy so much with a very low income.
