What ?? noo 

If Iran and Qatar continue to follow such a road, the world market expects something bad

I keep 100 coins on my wallet and want to block these 100 coins
How to do it?
That I could spend all that more than 100 coins
In Dash there is such a function to lock 1000 coins for masternode and all that was earned on the POS can be spent
This function is useful when you want something coins to remain at 1 address and not divide into an internal address

Example
I sent 100 XBC to my wallet
POS 2 XBC
Total 102 XBC

Now I'm sending 2 XBC to polo

As a result, the transaction is received

2 XBC on the polo
3.4 XBC to another address inside the wallet

How to do something that would not be spent out of 100 coins, that would not be divided into coins on the internal address of the wallet
