With current macroeconomic perspective in the whole world, my view is that crypto currencies might gain popularity and with it, increase in price. But, nobody can guarantee that in few years these currencies will still be on the market.
This is just being optimistic when it comes to Bitcoin's development or rather pure speculation, gaining popularity isn't really that straightforward when it comes to the current conditions on what we have now. I'm speaking about the pandemic and how it will change things around it, now people are promoting contactless ways of paying but they aren't promoting new ways like cryptocurrencies but rather the existing ones like credit cards, digital fiat wallets, and tap n go types of fiat based cards but nothing about cryptocurrencies as of now. So if we look at the current price of Bitcoin now and for an eye of an investor I don't think it is an attractive or a smart kind of buy specially when you won't have any kind of margin of safety with the position you will have.
