what is the reason for such a sharp drop in trading volume on exchanges?
https://coinmarketcap.com/currencies/shield-xsh/#charts for the price everything is clear everywhere price fell but here the volume just fell to almost zero. it is very difficult to really buy or sell orders that are simply distant from reality.
Because those who bought for 200-2000sat don't want to sell cheap and there are less and less fooled people left to buy. They still haven't understand that XSH has nothing to offer. It was and is a copypasta from verge without real dev (I'm not saying that Verge is better in any way). That's why masternodes are not yet implemented - no verge to copypaste and even adaptation from other MN coins requires some coding. But without real devs - it's impossible or at least hard to do.
They earned some money on first hype and could have payed some dev to release something - adapt some wallet, make site etc. But real development requires more.
