I think that of the three listed users in the OP, it is difficult to find a better candidate - although I personally do not visit the Altcoins board and I do not know if there are similar
patients there.
I wonder if Polo7 is the same person as OpenCryptoSystems.
It seems to me that Polo7, OpenCryptoSystems and cryptoboss2020 are the same person.
My candidate is
DashingAgentThis user is mostly shilling for altcoins in Bitcoin Trading board, but he often gives very strange advice and if you take a closer look at his post history he often contradicts himself. He also often asks for donations for his work, as if his posts really help someone.
US people are buying LTC while the other world is avoiding it
There are 6 billion people around the world, just eliminate the people who do not use the internet then there are 1 billion people atlest who use the internet which means that 1 LTC is for 119 people. If only an individual has the purchasing power of $1, we can say that LTC will hit $119 at least to be divided equally among all of the people. But big exchanges like binance and kraken only allow to trade minimum of $10, let say that everyone has the purchasing power of $10 then LTC will hit $1190 in the future but when we don't know. So without any improvement in Litecoin network after paypal adoption, we may claim that LTC will hit at-least $119 per coin and it will never ever return back below to this level. If in case it happens then some whale will only be selling it.
Will Crypto live forever or die?
I am asking that question because there is a possible World WAR after many years it is because US has raised the threats for many Christian countries and it is the only who'd empowered Muslims (terrorists) against the Christian, US is a biggest enemy of Christianity Since the day one. Just imagine that US sold trillion dollar weapons to Kingdom of Saudi Arabia alone who is a founder of many terrorist organizations including ISIS + Al Qaida along with the terrorists groups/organizations they created in Pakistan, US also sold weapons to Turkey + AE + Many other Muslim countries and raised a threat for Europe and many other Christian countries. The interesting thing which is seen is that that US did never raise an accountability for his weapon puppet countries like the Kingdom of Saudi Arabia and AE, So it is possible that all Christian countries may awake and there could be a possible WW3. If it happens then do you think that bitcoin will live anymore?
You believe or not but the future of cryptocurrencies are ETH and another one
You believe or not but the future of cryptocurrencies are Ethereum and another one which starts with the 17th Alphabet, why I think that that because it is strongly possible that any group or whatever I cannot specify because I do not want that it may happen can create a super computer in order to temper the blockchain and do the 51% of attack on bitcoin network which currently looks impossible due to the current hashing power but to increase his/their balance in bitcoin, they would need to manipulate all the blocks, bitcoin network currently has less blocks comparing to ethereum....
