In the Telegram group about Bitrad.io that I am in, there have been many questions about how to use Coin Control to re-group the coins in the purse addresses and thus achieve a better result in POS (Proof of Stake).
There are several ways to generate crypto-coins, the most known by all is POW (Proof of Work) that is used by Bitcoin and the second best known is POS.
There were so many questions that I ended up doing a small video tutorial to clarify as many questions as I could. Also, it works for any other crypto currency that works with the same POS system. The video is in Spanish but it has subtitles in English so do not forget to activate them in Youtube.
I hope the tutorial is helpful and good luck in the POS!
