If someone calls you to buy the Bitlayer helmet verification and tells you it's 800u for a big one, just block him directly.
Most helmets have already been verified a long time ago and are now waiting in the trading market for newbies to buy them. If you buy one, you're likely to become a collector and won't be able to participate in the subsequent ecosystem at all.
So all helmets can only be verified once. Be careful not to get scammed!!!
If you want to continue participating in Bitlayer activities, you can join the second phase of the booster, which consistently offers rewards and has many spots available.
