I don't think ethereum has significantly gone down in the past few days. It might have dropped a little bit but it is pretty fine, doesn't look that bad. Also even if there is a little bit of price drop, it would mostly be a short term thing,  so there is no reason to worry. Ethereum is a pretty stable coin and good for long term investments, these short drops should not affect, keep holding.

I don't think selling now would be a wise decision as bitcoin's price has just started to recover and it has a long way to go. If you do sell your bitcoins and wait for the price to drop again you'll be wasting a lot of time as it might rise above 20k usd. You'll still be getting profit, but you'll miss out alot of profit and then later regret it.

It might not be a good idea as of now because when there is a lot of traffic it causes a lot of congestion which ultimately leads to very long confirmation times as well as very high fees. So if a person would like to use a bitcoin vending machine during such times he/she would have to pay far more than the actual price of the product.

Exactly, bitcoins and other cryptocurrencies don't have much to do with helping the poor people. The main problem for the poor is overpopulation. I personally live in India and the poor people here have don't have a sense of family planning and their numbers just keep on multiplying. They need to be educated about this matter as it is pretty important. If they can't earn a living for themselves how are they supposed to take care of a family?..
Apart from educating them about this situation we can donate some of our money to charity, I think that is all we can do.

Well, it has surely become hard to identify which ones of the bounty campaigns are legit and which ones are scams. You can try asking the people here on the forum about their opinions on the specific bounty campaign you're looking out for. You can try visiting the project's website and read the details, community reviews, etc. You can't be 100% accurate but you can minimize the chance of getting scammed by doing these things.

Well, it depends. If you have some free time which you would like to use constructively and you are interested in a specific ICO which looks good and also you're running a little short on funds you can try joining the bounty campaigns. If you have enough of extra money for investment, you can try investing it in an ICO.

That is true. This might lead to a sharp increase in the price of bitcoins. This might be a good start as bitcoins became a legal tender in Germany, others country might follow as well. Some of the goods/services over the world have started accepting bitcoins as a method of payment and I think now their number will increase.

Well participating in bounties and airdrop would definitely be cheaper than investing your money in an ICO. But it might not be as profitable as investing in ICOs. If you have a good amount of extra money which you can afford to lose you can try investing in some of the good ICOs, but if you don't have enough money, it would be better to participate in bounties because you can't get much profit from little amount of money and there would be a possibility that you might even lose your money, so investing small amounts in ICOs won't be advisable.

Well there are a lot of people in this world and there would be many of them who would never agree with us, because of various reasons. Some people would be just lazy and won't feel the need to learn newer things. There might be a lot of people who won't like to invest as it might be risky. A lot of people might have actually gotten manipulated due to the negative showcase of bitcoins done by the media.
I personally think of bitcoin as a great investment option, as whenever it drops it always recovers and reaches newer heights. The only people losing their money due to bitcoins would be the panic sellers.

Yes, social media is a necessity for advertising anything now a days. Most of the people are very active on social media platforms such as facebook, twitter, reddit, etc. So, if social media promotion is done, bitcoin will surely gain a lot more publicity, which would result in a better growth and it would be more profitable to everyone who has invested in bitcoins.
But the problem about social media is that the number of false, fake, half-true news, rumors are increasing. Which might be due to jelousy of not being able to invest or various other reaons.Also, there are a lot of people who would blindly believe these rumors. So it has some good points as well as some bad points.

This information is not true and it was spread by the "out of news" media, news channels in India show this kind of half-true stuff regularly and you shouldn't blindly believe it. You should've done a little bit more of reasearch. The finance minister of India said that bitcoin, along with other cryotos is not a legal tender and they would most probably be imposing taxes.

Yeah, I think there might be a lot of such non-technical explanation videos about bitcoins on youtube. You should try those out. Even if the person doesn't have much knowledge about technology but, still know some important things about finance, economy, market,  he/she would be able to understand what bitcoin basically is. So you can explain it in 'non-technical' terms. It is simply an investment method which is pretty effective if you want to increase your money. But as some other profitable investments, even this has a little risk as the market can crash.

I personally think Ethereum with it's slow and steady rate of increase in value is very suitable for long term investments. You can try out different coins which are among the top 10-20 coins as they are the ones worth investing in. Even bitcoin would be a very good long term investment as it's price is on the lower side now, so you can try investing in it as well. Yes that is true, so just keep holding your coins and don't bother the price drops as it would eventually go up again.

This question indeed is pretty unpredictable. Bitcoin is still becoming more and more popular day by day and if this continues, the number of people using cryptos will keep increasing. It might be used as a common payment method soon, as some already started using it in such a way. So, I think bitcoin might never cease to exist unless it gets illegal/banned in alot of countries.

No, I don't think 'short-term spike' would be a good word to describe the state of bitcoin's value currently.  If you see the bitcoin's price graphs of over the past few years, you will see that whenever it's price has gone down, after some time it always has recovered and crossed the previous milestone.
So, I think hodling will be the best option.

Well, I think that is a pretty good news and it is a good sign which shows that bitcoin will be used more in time. I think this might encourage other countries to accept bitcoins as payment for services, goods which would be very helpful for the people who are interested in cryptocurrencies. More number of countries need to legalize cryptocurrencies and as  Philippines gave it a good start, this might keep increasing.
I can imagine a situation where people are using cruptocurrencies (mainly bitcoins) frequently as a payment method in future.

I think holding would be a better idea if you are busy with your job, etc. and don't have much time for doing cryptocurrency trading. Long term investments in good coins such as bitcoins/ethereum can be profitable as well as less time consuming. If you want to do day trading, make sure you are:-
1. Having enough time for checking the crypto market regularly for looking at the prices, etc.
2. Have enough knowledge about cryptocurrencies as it is essential for doing crypticurrency trading.
3.  Having some extra money which you can afford to lose as trading might have a little bit of risk as the market might crash.
Personally I would prefer long term investments as I don't always have a alot of free time, I don't like to take any risks and I am a bit lazy as well.

I think you should go for it. Bitcoin never ceases to amaze us as it always gets back after a price drop. You can also check out it's price graph from around 4-5 years ago till now. Also you can see that it has already started to go up, it reached 10,000 USD a few days ago and then it dropped a little bit, but I don't think it would be much of a problem as it started to increase again.
So, I would suggest you to invest it for a long term. What most of the good investors do is invest while the market is red, i.e. when the price is alot lower than what it usually is.

Yeah, the fees has surely dropped alot, which might make bitcoin more attractive and invite more number of investors. But, the fees might go high again in the times of high traffic. I saw the fees went down a few days ago when bitcoin's price had become a bit more stable and had stopped dropping down further, but as soon as it dropped a little bit more the fees were high again. So, I think this might be a temporary thing as there is not much of a traffic. Exactly, if bitcoins go as high as 20k USD again, definitely alot of transactions would be made and it would cause congestion, which would result in higher fees again.
