In fact this is true, Bitcoin needs a long time to confirm the transaction as it requires large fees and these are things that make a lot of people prefer to use altcoins like XRP, TRX, LTC, Dash because it is much faster and its fees are low compared to Bitcoin.
But I think this problem has been solved with the Bitcoin lighting network where fees have been reduced very significantly and the speed has become superior to altcoins as well but the Bitcoin lighting network has not been widely popularized yet.
