Dogecoin, an alt-coin released this last December, was originally devised to have a maximum limit of 100 billion coins in circulation. However, this limit was only a stated intention and never included in the coding of the cryptocurrency. After a lengthy discussion with the dogecoin community, the developer decided it would be best not tot implement a hard cap on the number of dogecoins produced. According the block-reward schedule, every 100,000 of blocks solved by miners causes the block-reward to halve, until block 600,000, where the reward will drop by roughly two-thirds to 10,000 DOGE. This is in contrast to bitcoin and other alts, whose hard-cap is often pointed to as an asset that will supposedly result in greater value of each bitcoin over time (as per supply-and-demand).
By choosing not to implement a cap on production, the developer intends to make up for dogecoin that is lost to crashed hard-drives and other lost private keys, and also to encourage those sitting on a lot of dogecoin to spend it or risk losing value to inflation. Critics of the decision claim that by producing the cryptocurrency indefinitely dogecoin loses its value as a significant store of value, while those praising the decision claim it makes dogecoin more attractive as a currency by encouraging spending. Only time will tell who is ultimately correct, but for now the only indicator many investers look at, the price, has dropped by 15%
