DGB-BTC to fall to -150 sats due to de-listing from Poloniex

This is not a guess (it is), it will happen exactly as this chart shows it (it won't).
De-listing of one of the oldest alt-coins in existence from Poloniex means anyone who owns this coin will be required to pay people to take their coins from them.
This is what happens when the CEO of Tron buys exchanges to centralize everything crypto.

Comment:

If you zoom into the chart, it's doing exactly what I predicted.
