I read all the posts and thought. Way of storing their assets in different crypto wallets and in small quantities suitable for me better. But if I need money, I can use a Bank debit card. I never thought about using a debit card crypto. I think to wait until better times. But still I was curious and will explore this topic more thoroughly.
For some people it makes sense. For others it doesn't. A lot depends on where you are.
For a long time in the UK there were no exchanges other than P2P and banks were, and often still are, extremely twitchy about any funds related to BTC. In those circumstances a crypto debit card is perfect.
If you live in a place with good exchanges with low fees and fast banking then a crypto debit card will be a needless extra expense. Some may still prefer to keep those funds separate though.
