It still depends on the economic situation of a country. Countries with good economic situation are most likely to adopt bitcoin for innovation and development (unless it's prohibited by the government or strict when it comes to crypto). While countries having crisis just like Venezuela might have a hard time to adopt on this since they're more focus about their problem. Unless if the government itself, want to adopt or hold bitcoin and crypto.
Also one factor to consider is the government. Whether the economy is doing good or not, if the government is against crypto, it'll be hard to push more people into bitcoin
Dumps and pumps are the major ingredients of successful journeys of crypto currencies. The only reason why real investors are interested into bitcoin and some other projects of crypto market is that they give sharp results in short terms. Either they increase or decrease in values, they usually are not in loss if they are stick to nice projects.
Is that you own view of cryptocurrency success? I think you have a very wrong view because that is not the way that bitcoin is meant to operate, if bitcoin is to be reliable as a means of store of value, buddy, it cannot continue to be a product if pump and dump, and the reason for bitcoin pump and dump is because we are having so many whales still manipulating.
I am not saying that the market cannot fluctuate, but when it fluctuates, the level of decrease will never be as much as it used to be when the whales manipulate the market to pump the price and then dump it. Bitcoin needs to also serve as currency, and with pumping and dumping, it cannot achieve it as people will be scared of buying it for payment and them receiving it also for payment.
