Hi Mark First of all, I am very happy to talk to and have knowledge with experienced people like you in this community. Thank you so much for giving us such an opportunity. When I look at Question Categories I see many options. Actually, I wrote to get to know and meet you, rather than a question. I teach in primary school. Now I'm looking at the articles you shared. How do you evaluate the peaks, dips and pugs of coins in cryptocurrencies?
