The way that some of these guys are talking is that they cannot make very much in their country, so sometimes there could be questions about busting your ass for $40 per month when a signature campaign may well end up paying quite a bit more, and maybe we can presume up to $100 per month, so I doubt that the volatility of bitcoin is as BIG of a deal is just making sure that they are able to stay in the signature campaign and maybe have a few months extra saved up in the event that they lose their spot.. so then there might be needs to figure out if there are supplemental cashflow areas or maybe time can be spent to learn new skills in order to be able to be paid more,
and so if someone is used to paying all of their bills from $40 per month then what would they do if they had $400 per month? What are they going to do with the extra $360 once they have established their emergency fund.. which surely is something that anyone should have in place prior to investing in bitcoin or overly holding onto bitcoin rather than holding in a more stable kind of way.. .. it is hard to generalize too much about what someone else should do about various cashflows and then how much they might be able to invest (or hold) in bitcoin once they are able to account for the expenses and their emergency fund... which an emergency fund is likely a reserve of cash that would cover something like 3-6 months expenses and then other funds would be available for other emergencies that might come up.. so maybe even doubling the amount in the expenses projections or adding on an amount, and anyone who is trying to decide these kinds of amounts would need to account for how confident they might be in theiir cashflows and their expenses that they have projected out.
