Minimum hashrate to find a block?

[nuggetbram]

As a hypothetical situation, what is the minimum hashrate/number of average miners needed by a pool to find blocks at a regular-ish pace (not days between blocks or anything like that) with litecoin?

What about darkcoin, or vertcoin?

Why not look at some litecoin pools and check the stats out. You should be able to see the pool hash rate and see how many blocks have been found in a given time frame.

Pool block rates seem to vary a lot. Some pools I looked at had double the hashrate yet half the blocks found by another!

What other factors influence the amount of block found? Is it just luck?

In many times, I see, myself only got blocks (1 miner only in entire pool) with my 400KH/S Scrypt Power.

The difficulty, luck and how quick you submit the found block all influence the chance of you finding a confirmed block. I know the pools vary but you can get a good idea of the hash rate needed by averaging them out.

Really though you need big hash rates to be solo mining any popular coin and you'd be struggling to get ROI I think. If you wanna solo mine keep an eye out for new coins with some potential and solo mine those while the difficulty is low.
