Different blockchains - different transaction speeds. If you are not happy with the speed of the blockchain that you use, exchange it for another one,
thank God everyone on any major exchange can exchange one cryptocurrency for another without much difficulty.
That's the benefit we can enjoy where there's a lot of exchanges in the market, they will provide liquidity to ensure we can trade anytime we want.
What's important only is that people will begin accepting not only bitcoin but altcions as well, based on my experience, I am more satisfied using DOGE coin for my transaction as its faster and way cheaper compared to other coins I use.
Though we cannot deny that BTC is the most popular now, but because of its demand the value increases hence fees follows, therefore it's not advisable to use for small transactions only as the fee is not worth it.
