You have masternodes in the description of the BTCU project. But there is no information on the number of required coins for masternode.
I have already provided this information: to obtain the status of a masternode owner, it is necessary to perform staking in the amount of 100 BTCU coins.
Given that a BTCU coin can be expensive, ownership of a masternode is the lot of crypto-whales. This is inaccessible to ordinary mortals. Where is decentralization here?
Bitcoin Ultimatum network consists not only of masternodes. Everything is thought out and provided. Therefore, everything will be fine with decentralization.
