zCash and Ethereum fever

During the last weeks we have seen how in shops over the world GPUs like RX 470/570/480/580 have literally disappeared and right now is almost impossible get one of thoses. At these moment GTX 1070 and in the future GTX 1080 Ti will suffer the same problem, so if u are thinking about get one these, hurry up, because probably you will not be able in a couple weeks.

The reason why this is happening is pretty obvious, Ethereum have increased his value from 1.50$ at the begginning of the year to almost 400$ at this moment. The same has happened with zCash, this January his value was 48$ and now it`s more than 400$.

In addition these critpocurrencies cannot be mined by specialized hardware like happens with Bitcoin or others, so many people invest on rigs and plug them at their houses. Nevertheless everything aren´t good news, with the increase on the number of rigs will increase the difficulty of mining this criptocurrencies, so in a few months small homemade rigs won´t probably be profitable.

At this moment the 2nd hand market of GPUs will be filled with GPUs like RX 470/570/480/580 or GTX 1070 that will be sold as bargains. This fact has already happened years ago, but that time was with AMD 290X. It will be a good moment to get a GPUs, because you will maybe get a RX580 for 100$, but be careful because that GPU has been mining maybe for months without stopping on a hot room and it will be a little damaged.

What do you think about this amazing increase on the critptocurrencies value? Will it keep? Will it decrease and fall? Let me know in your comments, I pretty apreciate them because Im beggining here. Please dont complain a lot about my English, I know its not the best but Im taking classes and trying to improve.

Greetings.
