After the recent bitcoinsv pump, I tried to gather some insights into what was going on their chain. I started by figuring out how many bsv, that had not been moving since block 556766 aka the bch/bsv fork, had moved post fork grouped by date
By aggregating per month, I found that most pre fork coins, moved in the earlier months.

but by looking at specific dates I found that a big movement of old coins happened on January 17, 2020

I found this transaction 5e3f6f5412b3162df8bcb3706aa5bd29833582bb5e45eb31c7a0f91695b8539d on the bitcoinsv blockchain that moved 269k bsv but what is interesting with this transaction is that one of the inputs come from this address 1BgatB78WrFLdCgnPnBqiDcNFFA46jkPZe which looks like a solo miner.
This address started mining on 2017-08-01 up until 2017-11-16. During that time, that address mined 3,785 blocks (around 15% of all blocks during that time frame). None of the bsv coins had moved until a few days ago. I believe this is likely a solo miner, and not a mining pool, because those coins stayed idle for over 2 years.
After doing a common input ownership heuristic, I found this other miner 17Wk4GPKw9nZ9PbspzaxN3fv1L2m9NA9dg that mined 6461 blocks from 2017-08-28 to 2018-08-31 that also participated in the 269k bsv transaction.
I am going to load the bitcoin sv into my neo4j setup to use transactions graphs and gain more insights but from what I have gather so far some of the other inputs in the 269k bsv transaction are linked to block rewards from bch fork day 1 (2017-08-01).
This pro-bch miner has incentives to make sure that there is no flippening between bsv and bch and is increasing the supply of bsv (around 8m/18m coins have moved on the bsv chain) to be sold.
Happy to share some of my work with other magic internet money data scientists.
