Well, I don't think they should blame you, you just showed them the way.
It is up to them to investigate and learn more before investing their money, you are not responsible for what happens to them.
However, it would be better to explain more and tell them about the risks of failing (they are your friends/family after all).

Bitcoin can't be used as a payment option while it still too volatil.
High fees is a disadvantage and an obstacle too, but volatility is the main reason why companies refuse to implement Bitcoin for payments.
It was profitable when the price was rising, but now, the situation is completely different.

Don't be greedy, that's the key.
You have to sell your Bitcoins when you need them in your real life otherwise, what are they good for!! you can't keep them forever.
It is always a good thing to sell when you believe you made a good profit.

It is not about owning too many coins, it is about owning the most precious among them.
Just buy coins you think they will have more value in the future and you can sell them at higher price or those you think you will need them.
Some coins may have ZERO value in a short time and thus you will loose your money.
Pick them wisely.

Many believe that XRP will overtake BTC, but despite all the partnerships you mentioned and maybe there are more others XRP still unable to overtake Bitcoin.

Also, XRP price decreased lately like all other cryptos, which is not a good sign.
Bitcoin can't be replaced by a currency backed and supported by banks.

Those are just excuses to ban Bitcoin.
The real reason behind banning Bitcoin and other cryptocurrencies is that those digital currencies can harm their business and minimize their profits, besides, they will have no control over their customers and thus, they will not be able to manipulate them.

Scammers are everywhere, on FB, Twitter, forums...
Any newbie can be one of their victims and any one investing his money should be careful and don't trust someone he does not know.
If you give your money to someone you knew through a FB page you will loose it and it will be impossible to get it back.

You are right, panicking will make the situation worst and the price will go down more and more with people selling their BTC because they fear a sudden crash.
But let's face the truth, we (most of us) have no influance on the market and even if we hold we will not be able to stop such drops.
Big whales can

No one knows or can estimate the number of BTC lost and that can't be used anymore because of the death of their owners.

To avoid loosing your money after your death you can hire a lawyer to take the required measures and make sure that one of your relatives gets that money.
You can also tell one of your friends that you trust about your private keys and tell him what to do when you are no longer able to access your wallets.

The Blockchain technologies can be used in many field, not only for making payments and sending money.

Besides, Bitcoin and other cryptocurrencies prices are not stable yet that's why it is not safe to use it for payments.
In the near future, we will see Bitcoin used as any other currency, I believe it can replace credit cards.

Hackers can earn alot from hacking big exchanges, they can make a fortune if they gain access to an exchange database.
The sad thing is that many new exchanges don't care about security and even a newbie can hack them.
There are many examples where customers lost their money because of hackers attacks.

I don't think the Egyptian government can do such stupid thing, maybe someone working in one of the Internet service provider companies is using his position to do so.
I can't imagine how much they can earn from that!

It is an old thread and I don't know if you already bought a hardware wallet or no, if you didn't, I highly recommand you to do so,
Lately, I lost 5K$ from my online wallet, someone stole it because I didn't care for security.
I will definitely buy one because I don't want to loose the few dollars I still have.

There are no signs for that, no rumors, no big news...
During the last month there have been no big changes in prices.
BTC price is fluctuating between 10K and 11K$ but there are new coins that can change everything and bring some major changes to the cryptocurrency market.

C'est une bonne nouvelle puisqu'ils ne considèrent pas la cryptomonnaies comme une menace, par contre, ils cherchent à réglementer ce marché parce qu'ils sont convaincus qu'il  a un potentiel et sera le futur de la finance et vaut mieux en profiter que d'essayer de le négliger. 

Je pense que se projet est un scam, on sait tous qu'il n'y aura plus de petrol après 50 ans, en plus le monde a changé et les nouvelles technologies n'utilisent plus le petrol comme source d'énergie.
La plus part des engins utilisent les sources d'énergies renouvelables ou l'énergie nucléaire.
