This is true, but you should know that altcoin's pattern are not the same as it was before, ripple was $0,49 a few months ago, but it went down.
I suggest selling, XRP always seems to go back down after a pump
Most of the most strongest altcoins have been pumped during the last few days, the same happened with ethereum, it did a x2 between yesterday and today, it was crazy.
I haven't seen anything new to warrant such a crazy rise.
twenty billion dollars are nothing compared to the total marketcap of all the altcoins.
I also don't see much on the horizon for it to maintain a marketcap above $20 billion.
