It is safe to buy funds from banks. Of course, the profit and loss of the fund depend on the fund company and the fund itself. For the convenience of operation, it is best to register an online bank account, which can save you the need to go through the bank window, and each subscription and redemption only takes a few minutes. Both have their own advantages compared to buying on the fund company website. The handling fee for buying on the fund company is discounted, but the funds need to be transferred. Purchasing through online banking is easy and safe.
