Yes, but IMO as long as the chain is still hashing and no-one has demonstrated the proposed difficulty time-warp the coin is still safe and surviving, for now.
Though this could change entirely at any moment, I suppose.
It is not safe. Bot owners (including you) can fork the whole blockchain, it is not what people call safety.Though this could change entirely at any moment, I suppose.
Only if they can overcome the production rate of the other bot miners, though. This is, after all, still a form of 51% attack.
Let's look at some facts:
* To date, our longest fork was 13 blocks, this is *significantly* lower than historical forks of most other "fast" coins, including in particular HUC - the closest coin to moto in many ways.
* There have been only 10 forks longer than 6 blocks, which is the "traditional" confirmation count for BTC at 10 minute blocks. (Considering we average only 47 seconds per block since block 8000, we should "expect to need" almost 20 times as many confirmations (120) for the same level of integrity.)
* The vast majority of forks are simple stales, 1 block forks. These are entirely to be expected at such a low block interval.
Given these facts I'd argue that (historically, at least) the coin has shown itself to be pretty damned safe and secure! Personally, I don't know of any other coin at all with such a high transaction confirmation speed and such a low fork rate.
