There are lot of factors that can affect the price surge of Bitcoin like some whales trying to acquire more Bitcoin or there are new investors that take the dump as an opportunity so its not just about the mining cost. Remember that the Bitcoin halving is coming so I'm guessing that a lot of things will happen and Bitcoin will become more volatile until the halving.

I'm also hoping that 2020 will bring a good season for crypto market not just for altcoin only. If there is good things to happen next year aside from Bitcoin halving then we might see the altcoin season, I'm also expecting that new investors will be involve in crypto space and help the market to grow.

I must say that the existence of stablecoins is pretty useful in crypto space especially for traders and some investors that wants to protect their cryptocurrency holdings though stablecoins are not good for long-term hold since the price have less fluctuation which is not advisable for someone that is expecting some profit from his/her investment.

There are thousands of altcoin in the market but only few of them are useful and even crypto people are having hard times to choose a good altcoin so I think it will be more harder for a normal people to learn about altcoins though OP's intention is good towards mass adoption for cryptocurrency.

Buy at dips as much as possible is the best thing to do because we never know what could happen next year, if its be a good year not but I'm very positive that we will experience a good outcome by 2020 because of the big developments that is set to happen next year, like Bitcoin halving, Ethereum 2.0 and more countries that will accept Bitcoin as payment method online.

I think that scammers are having a hard times these past few months because crypto investors are getting smarter as time goes by but for sure those scammer won't stop and always create new tricks in able to catch their victims. Scammers will always exist even in real life or crypto space and it will be hard to stop them but we can lessen their earnings if we gets smarter as well or keep learning about their new tricks.

Bitcoin already gain trust in crypto community since its the first fully decentralized cryptocurrency and that's why many platform only accept Bitcoin because they knew many people are using it compared to other altcoins but I don't see any good reason why they should delist all altcoins because some of them are still useful and have been improve for the past couple of years.

To OP, it will be hard for you to make a deal here since you are newbie and didn't mention any trusted escrow in your post. As other users suggest you can buy BTC in some exchanges without providing your personal info though there's a limit but you can do it daily as long as you have money to invest and its much safer for you because dealing with users here without escrow may get you scammed.

Exactly because sometimes its really hard really to detect at early stages if a new project is a scam or not so some people mistakenly advertise it without knowing what could happen in the future though I agree with OP. Supporters and hunters could make a big changes in crypto investment if they become knowledgeable and stopped promoting bad or scam projects to help out investors to stay away.

Well Bitcoin is the most trusted crypto at the moment but altcoins have made some improvement and continuously developing to provide better usage for everyone so we never know what could really happen in the future for altcoins but I disagree with OP that altcoins are only good for gambling.

Christmas is coming so for me its natural for Bitcoin to drop its price because a lot of people need money to buy gifts for their love ones. It happens every December each year and then it will recover after 2-3 months, maybe in February or March 2020 because this is the time where people usually looking for new investments.

Maybe start in basic like teaching them how to send, receive and store their cryptocurrencies. I also agree with OP's suggestion about having newbies to be involved in crypto related platforms wherein they can earn and understand more about cryptocurrency. Nowadays, crypto related platforms are easy to use that even newbies can easily understand how to use it.

Sell now and regret later only weak hands will follow OP's suggestion though there are some other reason to sell because of the coming Christmas but as much as possible its better to buy at dips and hold long term until Bitcoin reach a new ATH, no one knows when but I'm very positive that it will come soon.

If you're bored and you have a lot of money that you can afford to lose then gambling is one of the option, its gives you some excitement and chance to double your money just by betting. For me, the purpose of gambling is to provide some entertainment for middle to rich people to have some fun using their own money.

Well altcoins are more riskier investment compare to Bitcoin especially the new ones though few of them has potential to grow its price over time so I also invest with some altcoins that I believe in, considering that I don't have big capital but my priority for long term is still Bitcoin so I keep buying it as much as possible.

Chinese people are known to be good at doing business so if OP's saying is true that majority of Bitcoin is held by Chinese then it gives me more reason to buy it because I can expect that Bitcoin will surely boom in the next coming years since Chinese are very good at making some profits and really focused on what they are doing.

If Bitcoin falls down to $5k then I bet it will not stay there longer because for sure a lot of crypto people will invest and buy more Bitcoin during that time including myself. Anyone here who are in the crypto space for a long time knows that Bitcoin will eventually increase its price in the next 5 or 10 years from now so its worth to hold.

The adoption of blockchain technology is continously growing each passing years but still big companies like Alibaba are still hesitant to integrate cryptocurrencies with their payment system and I bet that they will just create their own coin/token instead of accepting crypto that is available in the market.

I think OP's question will depend on how addictive the person is because if that person is making a living with gambling and can support his/her family then for sure he/she won't leave gambling just like that but majority of people will choose their family because gambling are just there anytime you want while your family can leave any time they want if you don't take care of them.

Majority of investors of 2017 fell victim from scam projects and some of them may have pull-out their investment since the project they invested is not generating any profit or to minimize their loss and I think its one of the reason why the marketcap drastically reduced.
