The new year has brought in a large crop of new investors to the Crypto market and traffic is overloading capacity. This brings to light the issues surrounding these exchanges in dealing with the traffic of trading over 1000 crypto currencies. The Crypto market is exploding and the market is ripe for new innovation and development to handle this increased demand. This will be the decade of Crypto similar to the .com explosion of the new millennium.

In 1985 the first .com domain name was created. 30 years later we see the capability to access the internet in the pocket of more than half of the world population. 4.7 billion people now own cell phones. Bitcoin started in January 2009. Just 9 years later we see a market growing at a rate indescribable in market terms. We are seeing something that has never been done before. This is revolution of decentralization erasing borders and creating true free trade. It's exciting to be apart and wish everybody a happy day trading, investing, and using these new platforms.

Cheers,
