I'm mining on slushpool and planing this week to stop and going to try some solo mining at de.ckpool.org for some months since in EU de.ckpool.org i think is better.

Atm I have 50ths with my Antminers S9 & S7 and extending every month.

I also have some BTC that I'm willing to invest on renting some hash from miningrentals. I know it is up to luck still but more hashrate chances are better.

My question is with my 50ths and If I will rent 130THs for 100-200h should I start with all the max ths 180ths from the beginning or is it better to start first with 50THS that I have from my miners leave it for some weeks or months and then do a push with 130THS from renting for 100-200hours.

Thanks
