I think the bitcoin price will affect all coins including Altcoin .. and only slightly different but it remains influential and if the bitcoin price goes up, Altcoin and other coins will surely go up .. because bitcoin is the first coin in the world of crypto and the top coin among other coins and it will affect Altcoin and other coins ..
well, we can see it now. bitcoin prices are currently on the rise, I feel that soon this will have a significant effect on altcoin prices. I really believe bitcoin affects the price increase on altcoin.
If bitcoin price will start increasing its price then people will start investing money in bitcoin and will try to ignore altcoin, bitcoin is the best option for investment and once bitcoin price will get increasing its price then no doubt that the investors will taking more interest in bitcoin as compare to other altcoin.
