The basic and most important thing we.have to note here is: when these equipment's where built these companies research into how to improve on the technology which is a different case here. Bitcoin was built on a testing ground and Altcoins are built to match with the government policies, then don't expect these Altcoins to take or measure up with Bitcoin. Most if these Altcoins are built for surveillance which we all know them while others where built basically to scam gullible investors. Bitcoin is the true digital currency.
