I've always loved to be a miner too but the expenses of the rigs and electricity always discourages me. And if bitcoin surges to 30k, there is no assurance of altcoins recovery. Who knows it may even be the death of some alts.
If bitcoin reaches $30k surely we can expect the price of altcoins to grow further along with bitcoin. Until bitcoin crosses $15k I don't think there will be growth with altcoins. When it comes to mining, the present market gives mere profit if you're mining bitcoin depending on the electricity consumption charge. When it comes to altcoins it is time to risk, as there won't be much miners, the difficulty will be low. It can be used as the time to mine and hold large volume. If lucky you'll be benefitted, if not it's a loss.
