wapinter i thought just posted and i remember him as decoin bounty manager , if you have a problem with your money , that means you are dealing with the founder of decoin , you can try to contact wapinter maybe he can help you to connect directly with the founder of Decoin , i also have a bit of money there but i had forgotten about it.

this is for a lesson in your finances , better to keep in your personal wallet address or at least choose a reputable and clear exchange

in crypto there is nothing we can predict
