I used to advice people to go for Bitcoin when they asked such a questions. This time, i am going to warn you about Bitcoin. Don't get me wrong, i am a real Bitcoin fan and always supported it, but it is very important to put feelings aside and think rational when it comes to money. Segwit2x is a real risk for Bitcoin which is only a week away. I don't mean to be all negative but this is a fact and not many users are aware of that. Bitcoin will probably fine and make good profit for its long term investors, but i would still not advice anyone to invest in Bitcoin before such a big risk. ETHEREUM looks safer and more stable coin at the moment.
