The post by Broke_Trash also got Lu Wu thinking.
At first, Lu Wu found this post absolutely absurd, but then he gave it a second thought.
If the game Battle Online really does become famous worldwide, players from every country would choose to use their local currency to spend money in-game to exchange for soul coins. That player's words would be true then, soul coins would become a global currency!
By thinking that way, Lu Wu realized an enormous bug in the game, too.
The game had no well-secured transaction protection system.
For example, the 500 soul coins that Lu Wu sold to Ye Xue'er back at the beginning. It was, in fact, unsafe and he could have easily been duped.
Although there were many guaranteed transaction platforms currently, their complicated procedures and long waiting periods had caused most players to choose the easy way out which was to just undergo direct transaction.
