Many people asking why there are a lot of altcoins, and they suggest limits the altcoin making should be done.
The reasons why I don't agree to limits the altcoin aside from the reason of decentralization.
Here are the few;
1. The monopoly of market will be avoided.
2. There is a competition of prices in the market that can limit the price of the stellar cryptocurrency to overshoot.
3. Altcoins can cause unpredictable fluctuation of prices in the market. Fluctuation of prices result revenue for the traders/investors.
4. New and small investors/traders will be given a chance to trade in the market.
5. There is a healthy circulation of money in the market because hoarding/holding will be prevented.
6. Exchange site/market can gain also a suitable amount.
7. Bounty campaign will be continued to progress.
This are good lists. It's good to have many altcoins because each coin is unique in their own way. Each has a good service, product and project that they promote. Some altcoins are worth investing because they are good for long term run. If there's a lot of altcoin, monopoly of the market can surely be avoided, and there would be many choice for investors to invest to.
