No amount required, just the transaction, not like alphaI just found out that the minimum purchase is 2U, so buying 2U is enough. It's already 202CA, and exchanging 2U for 20U may be quite cost-effective Until the end of the event There are not many people participating now, and the profit can reach 20U. However, with more people later on, it is estimated that the profit will also decrease. After all, it is possible to operate with multiple numbers without gas or KYC!
