is it still worth to buy monero?
I buy a small amount every week no matter where the price is and haven't regretted it yet. Only wish I had been doing it sooner (as in before alphabay).
The next Alphabay will have a much, much larger impact on the fundamental value of XMR. For one thing, it won't allow BTC or ZEC (insert image of Cazes hanging by his belt in a Bankok jail cell). For another, it will grow faster and to a much larger size:. The pent-up demand will be enormous, and the fear factor involved in using BTC or ZEC won't be there to inhibit transactions.
But bootstrapping trust requires magic. How long that will take, I do not know. If it takes too long, a technical solution will emerge.
