Bitcoin have a huge value now of 2700$ and i don't see it going any higher (not on a astronomic way atleast)
i don't see it goes X10 or X20 higher like it used to be before. it doesn't make sense.
on the other hand i can see Altcoin get a X10 20 and even X200 higher.
last year altcoins such as Ethereum and Dash were very less. and look now..
it's the time to invest in altcoin IMO
IOTA and Ethereum clasic for example
How can it not be a good investment anymore when it is constantly on the rise and is predicted to be in the 6-digit dollar figure in the next years? It cannot easily be gaining a x10 or x20 growth because it is already in the thousand value right now. It will not take few weeks for a x10 growth. It will take a year at least. But remember it is bitcoin, the best among all.
