The BTC is the first electronic currency. The community, BTC's market is strong and constantly growing. BTC can affect the altcoin market price ... So I trust BTC the most.
Yes, bitcoin is the most outstanding and strong history background from it's beginning. That is the main reason why it still on the top and has a highest value ever. Keeping the fact that btc is the first known crypto around the earth to promote other newly arrive altcoins. Hoping that this will continue to survive this kind of virtual market.
