All adequate projects have only 2-3-5% of total tokens as a reward to bounty participants(exclude airdrops and etc.). When you see dump and you think that it was caused by bounty hunters - think again.
Some projects have huge private pre-sales Real private, where public don't even know about their existence. And price of the token on these sales can be 1/5 or even 1/10.
It is the choice of every participant to sell or not to sell. Someone takes part in it to earn money, someone - to earn tokens Not so many coins are worth holding, but if you choose the right bounty - bingo

Incorrect causal relationship. Increasing of ethereum price to $2500 will not result the increasing of Bitcoin price, but increasing of Bitcoin price always affect an ethereum price, and it will rise as a result.
I believe that both coins can hit these goals. Bitcoin already was 20k, it can reach it again, so I think more interesting comparison would be -
Bitcoin 40k vs Ethereum 2.5k, and not "can it happen" but "which coin will reach first"

That is normal. Remember how much ICOs were held in 2017, spring-summer. That time they had only the idea and approximate roadmap. And euphoria Almost all projects on ICO in 2017 took free money that they got even without advertisement. And it seems possible to make anything when you have millions of dollars. But it turned not so easy, because you need to fing specialists, you should highly reward them because they are unique people, you should have money for all time long development and etc.
And now its time to show the result. Those who made ICO only for ICO are failed, those who made ICO to make product - will gain all this market

This is not kinda correct to think that some actions on the market can repeat only because they already took place some time before. For example, why can't the market go up like in May last year?
In my opinion it can go down. Dipper than it was. Why it should grow now? Imagine a whale that sold bitcoin for $20000 and he wants it back. Would he buy it for $9k when he can make it on $4k for example?

Yes, Bitcoin is the main cryptocurrency now, not by capitalization only but it is the only cryptocurrency that is legalized in some countries as payment method.
However cryptocurrency is not only payment method or electronic cash, especially erc-20 tokens that you have mentioned. Some of them are utility tokens, such things that are being used in their ecosystem only.
And many people prefer to use altcoins for payments where they are allowed in cryptocurrency, not bitcoin. Because of the price of transaction fee.
All will spread with the time, don't worry. First time dollar itself was only in America, now it is the currency that everyone knows about

It is very interesting to read posts from the 2013 about Bitcoin and Ripple comparison As the history show us, there are many coins that have faster transactions, lower fees, higher supply, but they didn't replace BTC because they all don't have one important thing that Bitcoin has.
So I think Bitcoin cant be replaced with other coin, especially with Ripple which is not cryptocurrency as is. Or maybe it can happen in the future, maybe 10-15 years later.

Your check list is good, I should say that best points are to read the topic on bitcointalk and make a team research - maybe some of team members already have experience in different projects so we can check if everything is alright.
One thing I would like to add - check project's repository on github and see how often does the team make changes and develop the product. This will help you to see the real position of the project on the roadmap

When you see the coin is $2 and you understand the possible future of this coin, you can buy it right now or you can wait a little bit and see if your forecast is right - if the price went up you were right.
So if this coin is $5 now and you understand that it can go to $20 in the nearest future - can enter this coin. Yes, it is hard because if you were able to buy 1000 coins and now you can allow only 200 this prevents to make a right decision.
But think - someone sold bitcoin for $1200 and thought that he was the best player at this game

Mew is a good tool to create ethereum and token wallet. So it is not necessary to use myetherwallet only if you want to make a transaction. You have access to your tokens, you have private key and you can use it anywhere.
When you see messages about hacking or something else, you can just not log in your wallet or do it on another resource. If you want to check balance - just use ethplorer. And no need to worry about this.

So you believe that all that happened in December and all those rockets that were launched to reach x2 x5 x10 x20 and sometimes more were just because people cashed in before Christmas?
Seriously, that would be easier to explain if people cashed out before vacation because who wants flat. But there were rockets, there were so many moons. And I don't believe that it was made by people with real cash, seriously.
And thats the reason why the market should restore. And now we see real prices, but there are some highly overrated coins still.

Many crypto market participants bought btc or some altcoins just because they see the huge green bar on the daily schedule and they think that they can earn this one every day and bitcoin will always go up and up, especially after they bought it
Only two kind of people are successful on this market - those who buy crypto for technology and hold it for time limits not price, because they know that this coin will have bright future; and those who invest with clear head and have trading strategy. All other people will get in depression every time Jihan dump btc

I like to participate in Amazix bounties. It is only second program I participate in, but both campaign managers were great adequate members. They reward only those participants who make content.
I saw some negative feedbacks about Amazix, but they were from people who want reward from shitty content made in 15 mins with low views.
So I think I will continue joining their bounty campaigns, and they make very useful telegram channel for this

It is possible. But you are right with timeframes. And saying that it is possible I mean it can happen, but if I specify the percent of this possibility I should say that it is something about 95% that it cant be replaced as for me.
Bitcoin is type of cryptocurrency that was launched long time ago and it works still, without any centralization. Of course it can be changed, but with support of the most.
And as btc is the father of all crypto, it is the beginning of new economic movement - there always will be coins that are faster, cheaper, and etc. but bitcoin will be the one

If you search some coins that can easily be listed on such exchange and it should have great day trading volume - it is very difficult. Because exchanges with high volume don't list any coin.
For example for day trading I use Binance for a long time(since Bittrex was the lead exchange and binance was like another usual exchange) but if you want ex that will list your coin - try HitBTC. They have good volumes, not best but good, and they list new coins often.

In last summer and spring mining was extra profitable but also mining machines were expensive. Now the situation changed and mining get you less profit, and it cost cheap also now.
But no matter how much mining costs, I prefer to buy coins with a good project in the beginning of their path. You can sell coins immediately, but with rigs - it will be difficult(or very cheap) to sell them fast.
So diversify your portfolio and buy some coins for at least 1 year of holding

Experience in crypto is really, really cool especially experience in making projects on blockchain, but do you think that quantity of projects is the index of great team members?
As for me successful team is the team that make one project and they make it all the time, from the very beginning. When people change the team and make it not once, it makes me think about the causes of such actions.
But if you believe in the project, if they have good white paper and clear idea(and resources to convert it to project) - in that case you can go ahead not being afraid to lost investment

High risk. Especially now. I mean not phase of the market, instead I think it is better to invest now.
I talk about huge quantity of fraud coins and fake commands that just show that they are working on projects but they do nothing to make a project, only promises. And marketing of course
I prefer to buy coins from top. They don't show 1000x in few days as small cap alts can, but risks are lower. Top cant disappear from market in one moment while new alt - it can

You mentioned that you joined this kind of activity as a job, but airdrop is not job at all And maybe thats the reason why it is not well paid, or even not paid at all.
Airdrop was hype in past few months. First projects that used this way of promotion received huge returns and big strong community. But now airdrop projects(almost all, but not all) are just projects that don't have enough money for advertisement. So 90% of all airdrops is just the waist of time. Bounties are cool, here you receive reward for something you have done, translation for example. Join bounties and forget about airdrops

Solidarity. I think this is manipulation, in the last year(last spring) we saw what is real bullish market - all coins made x10-x100 just in the year, and then another bull run in December, that was crazy. I think that first pump will because of new adepts and new money, and the second one was with help of tether manipulations imo. Now we see very very weak rise for crypto. It is not natural, it can be made by a couple of millionaires on such small market.
I think it will go deep and real rise will be in autumn or something near that

I use to participate only in signature campaign. Half because I don't have big social accounts in twitter in facebook half because I don't see any advertising advantages of such promotions.
On bitcointalk - I understand - here are people who involved in crypto and who is searching for investment tool. In social media - maybe 1% and this is really, really optimistic number.
Translation campaigns makes me cry sometimes Not because of translation - because of people who reserves translation right less than 5 mins after topic creation. I don't understand how do they do it
