There has been some whale accumulation going on and they haven't spiked the price yet, so it still seems safe to get in before they do:
Where it says "not a lot of accumulation going on obviously" is not true.
Accumulation is going on the entire time during periods of what looks like no activity.
Monero deserves higher valuation but not until it becomes widely used in dark net.
Nothing is going to remove Bitcoin from darknet. It is still the main crypto used there:

There is already too much infrastructure made for bitcoin in darknet. You have blockchain exporer there, escorove services, bitcoin exchanges, mixers, scammers, etc.
None of the ppl involved in these services, e.g., mixers, will allow to have any other crypto to take their mixin cut.
