I was sent a bit coin transaction from someone who owes me money, to my cash app account. I know that cash app has a $2500.00 daily cash limit but supposedly an unlimited BTC transaction limit. I was surprised that the BTC transaction did not arrive, though it was a 5 figure transaction, and asked about it and was told by the sender that it was stuck and suggested that I open a new trust wallet, which I did.

Well opening a new Trust Wallet did not solve the issue so I was told I needed to link my cash app wallet to the trust wallet by making a $1000.00 transaction into my trust wallet, the transaction from my Cash App wallet showed up in the Trust Wallet and posted in the wallet balance but the pending/stuck transaction did not appear. I was then told to make 4 additional transactions of the same amount, $1000.00, to "stake" the wallet and this would allow the transaction to be released to the trust wallet. I got busy doing something else and came back to the trust wallet and my wallet balance showed $0.00. I finally located the transaction codes for my transfers and found out that the BTC was transferred out of my trust wallet 15 minutes after it arrived.
 
Well needless to say I do not have the extra $4k, to send down what looks like a black hole. They provided various screen shots from BlockChair.com showing both transactions in the blockchain and have answered questions about each part of the transactions that have been made since the initial payment and why its not in my wallet balance. I was asked today if I had made the additional payments to the trust wallet.  However, so far the crypto dots have not connected in my brain and I cannot find anyone I know with knowledge of crypto currencies and the blockchain, I'm 65 yrs old.

So the questions I have are:

1. Why did Cash App not accept the large BTC transfer, I have used Cas App over a year and have almost 100 BTC transfers equaling the amount that was owed and sent to me.?

2. Do you have to "warm up" a new wallet with some transaction history before it would accept something that might be considered out of the normal transaction amounts for the wallet to that date?
