If you have enough skill and great predictions on altcoins, then trading is the best for you. Sometimes you can earn 20x of your investment.
best investment apart from bitcoin itself is to invest those bitcoins that you have in promising altcoins. Bbut like any other investments it comes with many different,,
I also think it will be a good idea being involved and keep some ethereum. Even here on my country I can see ethereum's popularity, but mostly , they are just faucet users..
The price is debatable, but most people are buying into it thinking it will reach the same as bitcoin.
But I dont see any reason why it would, unless someone can educate me why its worthy.. I think all altcoins are risky though.
