I like bitcoin and love to use it to transact, but I much prefer to use it in other ways than while buying something from an online store or making payments online. It’s much easier and faster for me to pay an online service provider with LTC or Dogecoin than Bitcoin.
Don’t get me wrong; I’m saying this in terms of how much time it costs to confirm this deposit and actually release my order to me without so much delay for a second or third confirmation depending on the service policies.
It's up to you what you want to use for financial transactions, I believe that's entirely your prerogative.
No one has ever pushed for the use of bitcoin as a means of payment, but due to its several advantages over other payment methods, it's being used. You can set your own fees with bitcoin and you can send it without country restrictions. Faster transactions require a higher fee, but bitcoin can also be transacted at the suggested fee, although it may require a slightly longer processing time.
It's not a problem at all if you use altcoins for transactions, but everyone who uses bitcoin probably has other reasons than just transaction fees and speed. Bitcoin's scalability has been cited as a reason why some people don't use bitcoin, but this is simply a matter of choice for each user as there are always alternative options if you still want to use bitcoin as a means of payment.
