No, it is not and I will explain to you why...
… I can not advise anyone to invest in cryptocurrencies. We know too little about it at the moment. So, as a result, we can not invest properly with a reasonable investment strategy.
So now it's just gambling. It would be the same as gambling in a casino, most lose all their money. Bitcoin and all other cryptocurrencies could not exist in a short time and that would not be worth the risk.
My advice to you and to everyone who intends to invest in cryptocurrencies is the following:
Learn everything about this new technology and wait for the regulators and technology to establish itself. After that, a meaningful investment is possible.
I wish you all good luck and hope you make a wise decision :)
