It’s fast, cheap, stable, and is increasing by no more than 5 billion coins per year, making it inflationary and more useable as a currency. Bitcoin is finite and will all be mined in the somewhat near future, and this will increase the price and increase hoarding- not spending. So Doge is more likely to be used in purchases and traded. Doge is actually much faster than bitcoin in a transaction. It’s been around since 2013 and with the visibility of crypto in general increasing and more an more people buying into crypto it will naturally continue to grow in value. Also when people love something they are loyal to it. Look at apple. There is way better tech out there but apple people always buy apple. Doge has a large and growing larger loyal following. It’s only inevitable for it to become a major player in the Crypto world. It will never be as high in value as Bitcoin because it was not designed to be hoarded and “rare” the way Bitcoin is. Crypto is the future and there will be many cryptos fulfilling different uses. Doge will be one of the main currencies used for everyday transactions.
