DOGE and LTC may be the alternative to Bitcoin when prices stop growing. In the end, the price must reach a certain range before crazy heights become impossible. For example, it was easy for Bitcoin to grow 10 times in a month, and it is now possible within 8 years, and it may need 80 years in the future, while Both LTC and DOGE may be able to achieve this in a short period such as a year or two, but for this to happen, I think we need to wait until the price of Bitcoin becomes stable, for example in 2050, and then LTC and DOGE can be considered an investment for the future.
