Checked on Alphabay to see how Monero is doing there. Its not even begun and there are 75 pages of items from sellers that accept Monero, lots of them are accepting Monero ONLY. No need to brag any more, image is worth a thousand words

That's a great sign! With all of the old DNM's being busted by the fed's, this is a good indication that the rest of the markets will follow alphabay.
Also, is there any point in holding bitcoin? Or maybe reducing the core holdings of bitcoin and increasing the monero position.
Although I like Monero, please remember that it has not even a fraction of the proof of work protection and security of bitcoin. I've long considered that there will be one dominant "transparency coin" and one dominant "privacy coin".
I realize that Monero offers the option to be transparent, but I doubt it will ever catch bitcoin in that realm. Also the proof of work security promise of bitcoin will not likely be matched with Monero.
At a glance I would estimate that bitcoin could aspire to the level of the "above ground" market and Monero might aspire to the level of the "underground" market.
While I of course agree that XMR has nowhere near the POW security that Bitcoin has, I disagree with the other things, because the use-case for private transactions are plenty full in business settings. As a business you don't want competitors, customers, suppliers, insurance, NGO's etc. scrutinising your books (hence privacy) - but you would want to give authorities and auditors viewing access, but not spending access (hence view-key).
It also doesn't matter if XMR matches the BTC POW, as long as it is strong enough on its own (and it isn't yet).
