This is no April Fools joke, one of the largest South Korean cryptocurrency exchanges, Bithumb, announced it was hacked. Again. Hackers are thought to have made off with around $19 million worth of cryptocurrency in EOS and XRP, and the exchange suspects an insider job. The company operating Bithumb, BTC KoreaCom Corporation, stated that an “abnormal withdrawal” of the cryptocurrency was first spotted through its monitoring system at 22:00 Korean time (13:00 UTC) on Friday, March 29. After noticing this, the exchange allegedly “secured all the cryptocurrency from the detection time with a cold wallet and checked them by blocking deposit and withdrawal service.”
Or in otherwords: for small amount payments. Which would mean it can never replace the traditional currencies.
Yep, this kind of problem is common with low security exchanges, or centralized exchanges. It's a bummer, but it's part of the game...
The way I see, low security blockchain technology has been flawly designed to be hacked and hacked and hacked till total and complete demise.
