I believe there is only one type and thats Tier 1 to infinity and all of them is filled with bitcoin only. There is no other tier because it is just about the bitcoin and no other coins really. I believe in bitcoin a lot because its one of its kind and frankly 99% people are 100% holding some amount of bitcoin all the time. This means bitcoin receives its great support from small and big investors all the time and thus becomes the most traded as well as popular coin of all time. You might have created this list out of enthusiasm but there is only one exciting coin and its bitcoin.
