...with 4 graphic cards, ...2 on BTC throught nicehash,
how does this even work?
your GPUs are not even producing enough hashrate to be relevant when it comes to mining bitcoin! are you even getting paid?
I am not a miner but I suggest checking other altcoins for mining with your GPU, you may make a lot more profit than this because you need an ASIC to mine bitcoin. try visiting coinwarz and other mining calculator sites to get more information on this.
....
it all comes down to this and the way you think about it. I personally have no faith in any altcoin which is why I only have my long term investment in bitcoin but if you don't agree with my view then your plan is good enough.
as I said I am not a miner but I have thought about it. if some day I start doing it, then what I will do is that I sell as much to just cover the costs and keep the profit in cold storage. so lets say I earn 1BTC per month and the cost is 0.9BTC, that means I sell 0.9BTC and keep 0.1BTC (just example numbers).
Don't worry, I do not mine BTC directly with my graphic card, I leave that to ASICS. I use a software called Nicehash where you sell your hashpower to other people that pay in BTC. So I'm mining Ethash, equihash, neoscrypt and a few others algo depending on who is paying the most and I get some BTC in exhange. This is why people generally make the shortcut of syaing they mine BTC through nicehash.
I personally believe in ETH a bit more than BTC for long term but BTC is so important in the crypto world that I chose to diversify my portfolio to reduce the risk. This is also why I chose to add a "shit-coin" in addition as I often see the tips to diversify your investment and I totally agree with it.
Your strategy of selling what covers your cost and keep the rest is a common one. It is one of the safer one but the also one that has the less potential of a high profit. I'm willing to take a bit more risk by waiting a price slightly higher than what we have now
