Of course you can delete it.
BUT!
You can't delete it safely "forever". As this file is the blockchain and to see your actual balance and make a transaction (send SC) the client needs it to be synced with the network.
If you delete it, the client will start syncing it again. From scratch.
@Crypto_Ruwa I went ahead and tested it when I got home. While on privateinternetaccess.com proxy with username and password I had no trouble mining with marlin.
But now that I think about it you're probably talking about your browser. Probably can't do it that way.
@xurious I use M.2 and gigabit internet maybe that's why I never notice the syncing problems. I never considered that some people would have slower hardware. Good info.
Syncing on a laptop hdd or 5900rpm drive takes ages.
@whoami If you end up making a separate pc for mining you can use simplemining.net it's an ubuntu prebuild. Been using it about a month it sucks but it keeps running and running.
@blammas When I run marlin all of my 980s generally drop 3-400 mhs as soon as they start to heat up. But seem to make the same amount of coins give or take the 400mhs/card so I don't think it's a real problem.
