I was surprised to see Bitcoin transactions have been mostly stable and events like the Aug 1st fork, Segwit, higher transaction fees or other things didn't have a great effect ... even though the trend is pointing down a little bit.
Ethereum Transactions have started to overtake in Oct and with the launch of Cryptokitties the acceleration was even more dramatic from November 2017 onwards.
Litecoin is 3rd, BCH is still quite low and others like Dash and Monero basically non existent. I would have thought Dash has way more transactions after their big marketing campaign in 2017. DCR is picking up as well but their transaction log also includes PoS transactions which skews the numbers.
Let's see what 2018 will bring us.
