What happens if a miner processes my transaction that has not updated to Muir Glacier? Is it possible that I loose coins because the miner is still on the old chain so that the coins are now on the chain that ends up in ice age?
I am worried because I sent coins from an exchange to my wallet a couple of blocks after the fork (around 9'200'010). Maybe it was too early because some miners or infrastructure providers weren't updated at that time. According to "https://ethernodes.org/muir_glacier" still a lot of miners haven't confirmed the update.
So in general: could someone loose coins when doing transactions closely around the hard fork block height?
