Experimentation is part of BitcoinV mining. Mining at x32 is 32 times more difficult than x1. If you mine about 32 blocks every hour, expect about 1 per hour if you change the multiplier to x32. The early miners should really try and mine high reward blocks, but the current difficulty is too high, try lowering the difficulty level before mining really high multipliers. (Yes, you can lower the difficulty).
We just find a block with x16 in less than 40 minutes that's great !
To lower the difficulty we would have to just mine for a while with x1 ?
Or just don't mine at all until difficulty goes down ?
Thanks
No, you would mine at a higher multiplier such as x16 until the difficulty level goes down to a level you like. Keep in mind this is only really possible in the early stages of the coin (like right now). Once the difficulty level gets low (around 200k) you could crank up the hashpower and the multiplier to x4096 or something even higher and start mining a ton of coin.
