The bitcoin price is quite low at the moment. So it might be a good idea to buy more bitcoin at present.
and some altcoin have biggest potential growing
you can buying some old altcoin undervalued, then after azzure add it price will be rising to the moon.
The only altcoins that have any potential:
Monero
Maidsafe
Ethereum
Factom (maybe)
that's about it. The rest are all lotteries and I don't see any fundamental reasons of them going to the moon other than pure luck of holding some in between a whale pump.
it is all about the hype, and microsoft Azure adding them can only create hype that may or may not lead to a pump if there are some pumpers behind it.
also if feel like maidsafe and factom has been a side pump of the project ETH hype and exist in a smaller scale and doesn't really have any real potential.
