Optmism is a very helpful thing to survive in whatever situation hits the world. The pandemic made many people lose their jobs and made them lose their income. But I think the situation has started to improve and people can start again because the quarantine average is no longer enforced. Only maintain health protocol that the government continues to strive to implement in all daily activities. People can go back to work and make money.
In as much there is a change in the economy of a country due to a public pandemic, same should also apply to the citizens living to adapt to the change. The system isn't fair to anybody and so if you know how to adapt to it then you are liable to survive. Some businesses failed thereby crashing down people's plans economically, making people considering small scale business as a means of income.
As regarding to OP about considering in bitcoin and other Cryptos as a means of earning since you lost your job, its a thing of carefulness, its not onlynin bitcoin you could mean from, his about stock market, investment in gold and others.
