Very good post @grandpere, you always discuss about Cryptocurrency development day by day, I think, this is very useful for all of us, and especially for those who just joined in Steemit and not yet know more about Cryptocurrency. I'm sure, very many people in Steemit do not understand well about Cryptocurrency. maybe you agree with me this opinion.
With there are people like you who want to share about Cryptocurrency, it can help us all to know more about Cryptocurrency. Thanks for sharing @grandpere...
