Once you can see your NEXO wallet address there, send it over and they will display the amount you can borrow. The only thing I would say about borrowing is to perhaps wait a bit longer. We want to be SURE the market is in a consistent UPtrend before borrowing. Otherwise it may be hard to pay back... assuming you are going to do what I plan to do... which is buy more crypto and re-invest it.
All exchanges limit the activities of non KYC customers. Though I think most of them let you exchange small amounts still without giving up your ID. Exodus wallet lets you do exchanges, any size without KYC. But their fee seems large compared to exchanges. Not actually sure the fee is as I don't use this feature. I'm just a hoddler these day!
When I need to use exchanges I generally use Bittrex & Binance. Though this very much depends on what I'm buying.
