Obviously there is only BTC, and BTC will go up up and up just like gold did, the point is to not just hold, but day trade and predict the 100$-2000$ moves either way like I did few days ago, I shorted at 8100$ because by my TA it was time to crash, which it did after last spike to 8400 and a huge drop to 7125$.
BTC along with the next top coins are good to hold, they will not be in their spot for no reason. Having see BTC incline in price this past days can also reflect alts prices.
