Welcome to Bitcointalk and sorry to hear that you have lost your Bitcoin because stored those at an online wallet. I suggest you to move this topic to scam accusation as that's suitable board for such topics, and you should also share more details about the platform so others can be careful from such platforms. I suggest you to avoid any online wallet for storing your crypto assets especially your Bitcoin.
This board is fine if OP is only aiming to share his story but if OP plans to do it then scam accusation board would be the best board to post it and provide proof. It's unfortunate for OP to lose his investment on coinlender. In my opinion, this is mainly sharing his experience on that platform where he didn't get refunded even with just the original investment amount that OP put in the platform. I amndure it is a lesson for him as to never store bitcoin in an online wallet.
