This core concept of cryptocurrency is fascinating, and will change the world in my opinion. The difficulty however, is that cryptocurrency is still in its early stages, and has faced many growing pains thus far. For example, in December 2017 and January 2018, the Bitcoin network was so congested, that it would often take up to several hours to send or receive a transfer. Not to mention the fees that were very high. If for example, a person were to buy a hamburger for $3 back in January, it likely would have cost more than $3 in fees to send the payment, and would have taken too long to send. This showed that, at the time, BTC was not really scalable or practical. Since then however, BTC has been in development of the lightning network. The future does indeed look to be more scalable. However, it is still questionable as to whether BTC will be able to achieve the status of store of value, as well as transitionary currency. If BTC achieves the popularly forecasted price of $100,000 or even $1,000,000, it will be interesting to see how expensive the fees are. For this reason, it would make sense to have a transitionary coin as well.
