The subject of crypto coins is very much in vogue nowadays, but there is not much information for those of us who are not familiar with the subject to read and understand easily. I find those publications very interesting because they are an alternative to get to that information. Bitcoin is spoken of as the currency of the future and many are interested in obtaining them through mining devices and exchanges, but this, at least in my country is not very safe. The state has persecuted the people who have this equipment and has deprived them of liberty in many cases, so it is very risky to be a miner. Now, the government talks about Petro as a cryptomone, but with the little I understand about it, I think it is far from being one. Thank you for this publication, @techblogger.
