Let's me translate for you. Which exchange(s) list your coin? It seems there is none. So, he is advising people to be careful with your project

Do you guys have any idea what your coin is supposed to do? Looks like making money on the graveyard of failed crypto projects.

you haven't heard a 51% attack on PoS coins because that attack is specific to PoW. but there are lots of other attacks against PoS that you can find if you look for them and they don't apply to PoW.
But none have materialized as far as we know. So far, it has only been on paper.
Regardless, see with POS, one can have passive income while helping the network. But, with POS, hosting a full BTC node of almost 200GB of data provides no incentives. Ever POW coin will somehow end with over several TB of data, making it challenging for anyone to hold for free in the long run. Maybe the BTC devs should think of a way to incentive full nodes by adding some kind of POS. Dont you think so?

JPM coin is another altcoin in the fray of the myriad that already exists. they all compete on an uneven ground. some have more funds than other but I dont believe any coin is a threat to other. A coin is a threat for itself if it cannot innovate. Ripple is bringing something most probably JPM coins doesnt have. They are now learning the very basis of how crypto works and how it can be implemented in the banking system. I think ripple has a fair advantage. It has experience and lot of endorsements already

everyone including the expert traders were newbie at some point. Without newbie, there is no expert traders. Newbie should definitely trade. But, following a mentor can greatly help

Interesting project. But need more informations especially on the qualification of the funders. None of the linkedin profiles seem to work. It says This profile is not available. Please fix it.

POS and POW have both advantages and disadvantages. But, it is safe to say that POS has more advantages compared to POW. To date, I haven't heard much of POS coin being victim of 51% attacks or the likes. And rarely would you hear of hacks in POS coins. Is POS the future of cryptocurrencies? Any advice on which technology to invest in will be welcome.

Any one can inherit your crypto if they have the private keys. Conversely, no one can inherit them if they don't have the private keys. A will wont help in that case.
