Try not to recharge such a small one. The smaller the one, the more troublesome it is. The cost is higher and the handling fee ratio is higher.
If you recharge the solution: First, cancel the previous recharge order on the website.
Second, place a new recharge order, and the final amount after adding the random number should be equivalent to the small amount that was charged before.

Method for exchanging U for a customer's first recharge power: (The principal is purchased on the exchange and is limited to three days. However, the recharge power cannot be transferred out, which will not affect the transaction)
1. The website has tutorials on how to buy U. Buy U below 50 at a time (there is no limit to three days), and buy them three or four times to gather the required computing power
2. You can find friends and acquaintances to exchange for you, or you can exchange with us. You can use it directly.
3. Partners usually buy more U by themselves and save it for use. The user does not have enough U to replace it with him. That is, it costs 100 to 200 U or your own rebate charges the corresponding u. You can use the rebate to directly transfer them.(Direct and indirect customers) You can also get a rebate on this computing power.
