Is investing in cryptocurrencies a job you can live from?

I got the first post to resteem, but it was no job offering.
But because it was the first money coming in I chose some different way:

If you are lucky enough, you could live easily from the growing market of the cryptocurrencies. But it is really difficult to see all the details about the cryptocurrencies and invest always right to gain enough money to live from it.
To my mind the Bitcoin might not be used for this kind of game anymore because big investors are influencing the price very strongly now. And if you are not such a big investor it is really difficult to make some big wins despite you are investing in the right altcoins.

This is the article who inspired me to write this and somehow sponsored this:

The author expected a nice rise of BTC and it occurred but after a short time this rise ended already. I hope he will be right and the next rise will start soon and stay a wile...
