It sounds interesting, I'll bookmark this thread to come back to it when it is up and running to check it out. If it gets popular, you are going to have to deal with a lot more traffic than the 20 or so users who have clicked on this thread would generate though.
My only concern from your initial post is this feature:
Notification system that follows big whale wallets for large transactions that might affect overall market (Captain Ahab Alarm)
The "Whale Alert" account on twitter which essentially does what you are describing here is panic-inducing nonsense. 99% of the trades it reports are exchanges (or other services such as web wallets or casinos) either moving from hot wallets to cold wallets, cold wallets to hot wallets, or sometimes cold wallets to new cold wallets. The small number of trades that are actually from individuals are almost always them also moving funds between wallets. The
very rare times that one of these alerts is an individual making a trade, it is always OTC. Despite all this, every time they put out a tweet, there are users on here, on reddit, on twitter, who panic that the market is about to "crash". During Coinbase's upgrading of their cold storage last year, despite announcing it beforehand, making blog and twitter posts updating people to how it was going, and the addresses involved all being clearly linked to Coinbase, "Whale Alert" still managed to panic a bunch of newbies in to selling their weak hands.
If you are going to implement a feature like this, could you at the very least use the list of exchange addresses from walletexplorer.com or similar so you can ignore movements which clearly will have no effect on the market?
