BTC has crossed 29000. But compared to that, altcoin didn't pump much. And now the BTC domain has increased a lot. Normally, when BTC domain increases, altcoin dumps and when BTC is stable, altcoin pumps. May pump price in January and February.
The altcoin will have its time to get pumps, and that will comes soon. You can wait for that time, and you can buy any potential altcoin from now on before the price increase. The increase of bitcoin price seems will not stop for $29k, and I think that can continue in the next year because I feel that the very highest price does not yet break. The market situations now become green and some altcoin can increase for a small price, and I think it is good for you to make a scalping trade, but be careful.
