Now since litecoin has 30 less value and 4 times more blocks to secure the received transaction that is equivalent to 1 bitcoin block you have to wait 120 litecoin blocks. So bitcoin is much more secure. (Note that proof of stake has precicely 0 security because one or more past stakeholders can use their stake and reorganize the chain from the point before selling at 0 cost)
This is completely wrong. Assuming the same orphan rate and the same hashrate share among honest and evil miners, one Litecoin block is as secure as one Bitcoin block. The mean block interval is irrelevant.
There has been lots of discussion on this topic. Please search.
No that's simply not true and discussed a lot of times. Based on your logic 1 bitcoin block is as secure as 1 litecoin block which is as secure 1 block of feather coin (which has been attacked multiple times) etc..
There are no evil and honest miners. There are those seeking to profit from honest mining and those seeking to profit from double spending. If you receive 10000$ and wait 1 block to credit the senders account with bitcoin you will be more secure compared to the other two since it will cost more to reverse the transaction (at current market valuation).
Anyway as I said in my previous post this thread is about block intervals and decentralization and not block intervals and security. Please don't troll the thread.
