Hi respected sir, @v4vapid, I read your article 2 times to understand it, Bcz I am new here so don't know much about it. You gave a comparison between centralised and decentralised, I think it's about transaction fees BTC which is too high, I only invested in some altcoins from my steemit earnings. BTC is going high and high bcoz huge investors buy it. Thanks for updating very useful article and point out issue.
