This was one of my first platform (incl. non custodial wallet) I started using which supported the 4 main crypto (BTC, ETH, LTC and BCH). They have added XLM and presented quite a huge airdrop of the XLM. Moreover later there were STX airdrop. These promotions were good that I was attracted to the platform and stick with the wallet. Over the time it got worse. I have been forced to use the customer center services as I hadsome bug with my wallet and nobody was able to help me (I have found out that they have issues on their backend). They have not added too many new crypto. It was obvious that the competition is far ahead and Blockchain Wallet is starting to loose their position. If you want to buy the crypto, you have to pass KYC and the fees are quite high. The interface (frontend) is not user friendly, in my humble opinion, and sometimes you are lost. I am using mainly different wallets now.
