I have had a Blockchain wallet since Sept 2017. I HODL funds throughout the past 3 years. In early 2020 I opened a Blockchain exchange wallet and I have been holding BTC and trading (selling/buying BTC) for most of 2020. Once you have your bank account linked I have experienced near instant buys and sells which blows me away on the speed. Last night I raised a query on the chat feature and must say that the guy on the other end was great! Fantastic support to help resolve an error on my side (I needed to do a firmware upgrade on my Trezor wallet). Blockchain - Keep pushing the boundaries of this fintech space!!
