Bitcoin always 10 steps ahead.
20x difference between best altcoin.
It's not difficult to choose.
You can say that again, bitcoin really is in dominance when it comes to any Cryptos out there, you can pick all of them when particularly trading but bitcoin will remain on the top of the food chain, but if this is all about Altcoin then I prefer Ethereum all over other Altcoins, you can see that it has a potential not to overtake bitcoin but to be on a best of all of them out there.
Bitcoin is very dominant as you have said. I think because its the first coin so people will trust this coin better than some jokecoins. Bitcoin was also my first coin so i 100% believe in it.
ETH and LTC are not so bad coins. I had ltc once i converted to btc because i wanted more bitcoins.
