not a bad idea since you already have the tools,and it was only stocked in your room then better use it again,yeah mining is very expensive and we cant find profit but thats because the prices of cryptocurrencies are in lower level.
but once we take at least more than 2017 highest capitalization?i am pretty sure profit can be generated in Mining again,but for the mean time you need to extend your capital because it will take 6 months before we finally reach the Halving and see the next bullrun
This could be a good idea if the average expenses for mining are lower or slightly lower than the total profit of coin generated. But if it is higher than by a big margin, why do not you just buy it directly on the market and then hold it. I do not think it makes any sense to keep running the mining hardware if you are losing your money for 20% or more, we need to act smart in managing our money.
By doing this we can save some money or increase our holdings, we can start mining it again after we think it is fine to do it.
