I don't think so. It even helped to introduce to some people the blockchain and cryptocurrencies because of their habit in gambling. More people are now aware and they can use it to gamble online. Maybe some of them are now investing in crypto because they learned the potential of it in the future.
Any valid source? Gambling online is not always crypto-gambling.
People become more active in online gambling but do you really think more become an enthusiast of crypto-gambling online?"
And for a gambler, I doubt they really care for the potential on crypto by investing in it. They gamble to win, not to hold it for long.
The demand for crypto is increasing along with gambling Covid-19 hurts the country's economy but has no effect on crypto and gambling.
Let's face the fact that crypto is not helpful in a time like this. It can't use much for food delivery online, purchasing essential things, basic things since there is the only few merchant that accepting crypto payment that much directly.
Good thing there are exchangers that convert BTC to fiat. But not all countries, do have a service like this.
Online fiat payment is the one that most used today. More convenient and fast.
