Nowadays I am very carefull to invest in bitcoin related ventures.
I think there are no person that is able to lost bitcoins just for sending it to a wrong bitcoin address. Because as we are going to send our payments it is our responsibility that we need to check the address properly. And with my lost, I lost my bitcoins because I became a victim of a hyip site for one time only and that taught me a lesson.
The only way to send it to a wrong address is if there is a Man in the Middle attack, and the attacker gives you a wrong address.
Since nobody types out bitcoin addresses to send to, there is a very less chance of making a mistake.
