Re: blockchain problem or not??

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.

Whats the best way to get out of this??

Dont use services that have shitty software to handle payments. Its not your responsibility to fix their software. The only thing you could do now is to follow the chain to the first unconfirmed transactions (it forks off into at least two chains after a while). Once you have a nice list of transactions, get the raw formated version and broadcast them via a website that allows you to do so. From the last instance I have see, I think you can easily expect >>400 transactions to be involved. Might take a few hours by hand.
