The inputs of the those transactions isnt confirmed yet, you have to wait until inputs got confirmed first then your trans could get confirmed too
I didn't understand, can you explain more in detail? How long can this take to confirm the input?
What causes these type of problems??
The ponzi you expect payment from has bad software to handle the payments. They use unconfirmed coins to create a TX on top of it. The TX on top can only confirm when the earlier is confirmed. This can be in the same block.
Lets take "bx2.club --> rajat08" as an example. In blockchain.info's advanced view[1] you can see a little red "U" for unconfirmed. If you click on the link labeled as "output" next to it you will see another TX, which is unconfirmed. The chain of unconfirmed transactions that depend on eachother in this case is rather long. I would suggest you stop using the shitty service that created the TX, but seeing that it is a ponzi I have little hope for you.
