İf you have used bitcoin before, you should know what is the idea behind it. İf you don't know lets see it quickly;
Satoshi Nakamoto is a founder of Bitcoin. He gave us a big chance to fix economics problem. What was Satoshi's idea and why did he/she create this currency ? This information was taken from Bitcoin Whitepaper that was published by Satoshi Nakamoto.
Abstract: A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution.
İntroduction: Commerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model.What is needed is an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party.
Now, you know the main idea behind Bitcoin. İf you don't trust third party like us, you can take your economic control from them with using Bitcoin or other cryptocurrency.
Unfortunately, Bitcoin or other cryptocurrency can't be use widely in all areas of life. Because of that we have to use exchange platform as third party software to exchange it for a national currency. Most people used it for centralized exchange platform and they are third parties just like Satoshi complained about it and wanted to solve the problem. There are no differences between banks or other third parties that used it for physical money.
You must understand the importance here. These sites are not reliable, they can steal your money, they can be hacked by hackers (like Bitfinex and MtGox) or they can cheat with pump-dump strategies so they can make balloon price for altcoins easily on their platform. They are not safe to use your cryptocurrency.
Using an exchange site as third parties are coming completly opposite Satoshi's purpose.
Everybody's know that, when poloniex announce a coin will add on their platform, the coin price will increase minumum 2x maybe more. This problem we have, it is not only because of Poloniex also Kraken, Bithumb and other centralized exchanges same with each other. They only add coins for manupulation and steal your money. You don't have any option to share your opinion. Actually they have a request form but they don't care about it. :)
We had a CarpeDiem Coin, it was trading on Poloniex. The project for that coin was totally scam but poloniex prefered to keep it on their platform. Until they pump it and stole the money from users , they deleted it from the platform.
As Another Option is Using Decentralized Exchange
A decentralized exchange is an exchange market that does not rely on a third party service to hold the customer's funds.
Why we should use a decentralized exchange?
Centralized exchange sites are not safe. But with decentraliezed exchange you can trust yourself to be in safe. Then centralized exchange sites are not transparent and they can share your identity information. But with decentraliezed exchange you don't have to share your identity to trade with big amount.
İf we talk specifly, you can see the Waves purpose with their project. With waves dex you can exchange your coin P2P and you can lease your coin to earn fee with LPOS system. The other options will became in future like:
Miner Reward Token: miners will be able to vote for certain network parameters and issues, similar to the proposed scheme for Waves Community Token.
Waves Community Token: WCT holders will be able to vote for different projects.
That mean it will be totally decentralized. And community will be able to choose what if they want.
Already you have option to use decentralized exchange now. You can use Waves,Bitshares, Nxt ...
But don't believe that centralized sites
