My favourite coin is Espers right now.
it is a really good coin with a great potential. The last two months the dev has been missing for Real Life issues and thats the reason of the preice drop. Despite that now they are working hard again on Espers. On November 1st there is an update that fixes the POW difficulty.
In my opinion Espers has a great potential. If they someday achive site on chain(the main feature that espers will have), the coin could easily worth 600 sats(right now only two sats so great profit could be make.)
