Over the past few weeks, we have seen both Visa and Mastercard crack down on cryptocurrency-related activity. The suspension of debit cards issued by Wavecrest has sent shockwaves throughout the cryptocurrency community.

More specifically, there are a lot of customers complaining about extra fees when buying cryptocurrencies on Coinbase. This mainly affects Bitcoin purchases, but it is certainly possible that purchasing altcoins could yield similar results. For some reason, using this exchange may now cost an additional 3% of the purchase price, even though Coinbase itself is not charging this fee. Instead, it seems both Visa and Mastercard have changed the “status” of Coinbase – and potentially other cryptocurrency exchanges – in their system.
