Of course that can happen, because the cryptocurrency is like a gift box that we cannot guess the prize inside correctly and so does cryptocurrency we cannot guess with certainty when it will happen even though it will definitely happen (my estimate next year) but if the Ethereum price is going on Bull Run then I am sure just 1 hour the price of Ethereum can break its highest record, because cryptocurrency price movements are very fast, so the most important thing to invest in Cryptocurrency is we have to see opportunities, for example like now when Ethereum's price goes down this is a time when we have to buy more Ethereum and HOLD until the price increases very high.

never worry about Bitcoin, because Bitcoin is the strongest cryptocurrency and will be able to survive at any time. then about Bull run, you don't have to worry about Bull Run will come or not in this year, because I'm sure Bull Run will definitely come in this Q4, because it's still October then there are still 2 more months to make Bull Run come in 2018, so I suggest just to be patient and wait for the presence of Bull Run in Q4 2018.

I choose top three altcoins worth investing is :
1. METM
2. MAS
3. NPXS
I chose it because I'm sure the price could rise high in the future because the function of the altcoin is very useful for the future, so that the price can increase.

Altcoins that are suitable for investment are altcoins that have a good concepts for now and in the future, and I suggest you to invest in METM, because the concept of METM is very good and useful for the future.

if you are a beginner then I would suggest you to do a bounty first, and after you get payment from the bounty then the result of the payment I suggest to be used as trading capital, because in this way the income you get will increase.

I advise you to invest in ICO Module, because I see this ICO has a good concept for the future, you can check this ICO on the website https://modltoken.io, so you can read the ICO roadmap and whitepaper (maybe you interested to investing in this ICO).

in my opinion Ethereum was not struggling, but was waiting for the right time to surprise and Ethereum let everyone underestimate Ethereum because the price continued to fall and now Ripple can beat Ethereum, but when at the right time everyone who underestimated and not believe with Ethereum will surely regret that because Ethereum price will increase very high.

yes, all you can do is in two ways, that is as you say
1. SELL
2. HOLD

but I would suggest you to HOLD, because if you sell it you will lose 80% of your money, but if you HOLD it is possible the price will increase when the market price recover, even though it takes a very long time, but HOLD is the right choice than you lose your money.

altcoins that I believe and will not sell are METM, because I see the function of this coin is very good and has the potential to make the price rise very high, so I always buy METM and hold for the long term, because I believe the price can very high increase in the future.

if I personally would definitely buy a coin when the price goes down and sell it when the price increases 5% to 10% of the price I buy, I take a small profit because I just want to take a small risk, because if I wait for the profit I get by 20% or more, the risk for the price to fall is very likely to occur, so I better sell it when I get a profit of 5% or more (maximum 10%) to make my money safe.

still profitable, but if you choose the right ICO because as we see many ICOs that fail don't even reach softcap, but there are also ICOs that achieve hardcap and are successful, even the price goes up very high when entering the exchange, so if you want get a big profit then you have to really choose the right ICO, so you don't spend your money and time to invest in the wrong ICO, and my advice to choose the right ICO is :
1. The project from the ICO is very good and useful for the long term;
2. Clear and appropriate Whitepaper and Roadmap;
3. The number of investors is equal to the number of members in the group (such as telegram, facebook, twitter). for example: sales have reached $ 3m or more but the group of ICOs is only under 1000 members;
4. The admin and members in the ICO group are active, because if the admin is never active and never updates about the development of the ICO or the project, then I suggest not to invest in the ICO, because most likely the ICO is a scam, then the members in the group are also active because if the members in the group are 10k or more but never active, then that doesn't make sense.

in my opinion not all altcoins are shit coins, because there are also lots of coins that are priced up, so that proves that not all altcoins will be shit coins.

what I do is look at the situation of the altcoins I have, if the price goes up then I will definitely sell it and if it goes down I will definitely hold it, because only that way can make me get profit.

and why do you see Dash as a serious competitor? because from the rank of Dash is ranked 11 and Ethereum is below the Bitcoin rating which is ranked 2 so in my opinion the real serious competitor is Ethereum and not Dash.

surely it will happen, even though the time needed is very long, because the decline in Ethereum prices is very high, so to repair it will need a long time.

yes, because if the bounty hunter is not a job then we will not be paid to promote the ICO, so in my opinion bounty hunter is a job and we work as marketing in this forum to promote an ICO.

if I don't think so, because bitcointalk.org is still the best and no one can replace this forum, so in my opinion moonforum.net won't be the next bitcointalk.org.

all you do is look for the bounty signature that receives jr member, then register on the bounty and use the signature from the bounty, then read the rules in the bounty (so that you are not rejected because it is not in accordance with the rules of the bounty).

if I look at the market volume and statistics/graphs between ETH and BCH, then I would prefer to invest in ETH because I think ETH is better than BCH.

what I do with my token bounty is HOLD and I will sell it until the price rises very high and indeed gives me a decent profit
