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.
Buying old coin thats undervalue has so much risk than buying new alts,when you buy new alt coin you can see profit fast.
it doesn't matter if they are old or new. as long as there is enough volume to be considered alive (and not a dead coin) you can find a good old altcoin and buy it low before the rise and sell after that. especially if their price is low like 100 satoshi the rise will give you a good profit.
the new altcoins have more rise and fall but they are more risky also since next fall might be the last of the series.
