i think bitcoin is number1 coin and has good potential in the future. However, the bitcoin price is very high and I can not achieve it, so I prefer litecoin because it is more affordable and good enough for short-term transactions.so both are potential coin.
I also agree with your opinion, bitcoin does win the number 1 ranking from a number of other coins, but many people cannot afford to buy it and choose to try other coins, like altcoin. altcoin is an alternative coin, just a term to call crypto coin besides btc, like Eth
