Lots of scams through bounty.
All I can do is check out the bounty manager's experience. if in the history of the post has done a lot of successful projects. I do not doubt it.

I think no, bounty avatar does not help much. can not provide active links and make it difficult for readers to have to write links manually. And the size is limited, it is not possible to load all links related sites and social media from bounty related.

I think you also need to look at some other types of coins in different markets. If all the coin prices get red then it is normal. Because the price of all coins is interrelated. Only 1 to 10 percent for the difference of each type of coin

I guess your question is less objective. Throughout the year has been a lot of bounty that was launched and got success. And it has all been done with careful planning beforehand. If you have a good program from ICO they make, you do not even have to question this, because they can do anytime with a big chance of success

Since the beginning of January the price of BTC and followed by another coin that has experienced a drastic decline brought the impact of the stability of the price of crypto in the next few months to the present. And I think this is also a signal to explain that the price growth that every crypto currency will experience with a 1-3 percent daily rate continues until we get good news and that is inversely proportional to the past story to drop the currency price of crypto

Of course will get floating answer, there is no certainty even ICO that seems good. Can only be read after they reach hardcap at the end of ICO. And most importantly, do not forget the schedule and allocation of payments for campaign participants that have been planned since the release of the bounty program.

If in telegram they say they have succeeded in mission, of course you can see its own truth from history of their smart contract transaction then match with token sale chart on web available. if they are not a scammer then the smart contract they post is their reputation. If it does not transact periodically during ICO, you should leave the bounty at that time.

Some bounty limits participants who gain negative trust for signature campaigns and bounty & ANN translations only. And not for other campaigns for outside forum work such as social media, web translations and more. You should be more diligent to find it all in a bounty board.

Suggestions, it's good you also include the start date and end date bounty. Sometimes the manager does not include it on the thread and many still ask the telegram group. If you could find that information on every list it would be better. 

Even MEW itself has explained in its website that MEW is only a service interface to display user assets and assist in a transaction. there is no responsibility on the part of it related to loss of user assets.
So I think the security system offered is also standardization of security in general. For better security, depending on the users themselves how they keep assets safe.
But there is no other choice if we want to transact with the token ERC20 must use MEW which I know is the only service.

In fact I can not find which airdrop that has a nice token, really worth while listed in the market, even though it has been published by a trusted manager. To find a trusted airdrop, I think it's even harder.

Oh, you do not feel that time has deceived you. The market only shows prices on every offer made by all BTC users.
And if you're going to sell today it's a fatal mistake. Just wait for the right price to sell them all, the market situation will soon change while today many people are buying bitcoin on a large scale. This purchase will recover the bitcoin price

Because bitcoin prices fall, so many people will swap their ETH with BTC to boost back bitcoin prices. You know BTC is the most influential on the price of all the coins.
Calm down, it's just a while. If BTC returns up, ETH will soon get its high price again.

Good, from what you mentioned besides BTC and ETH (both of which are currently my best choice for a pretty tedious time, say 4 months ahead). I'm really not sure you'll hold them back. how are you sure will make you lucky by holding them back?

You can monitor the progress of bounty on the ANN board and their telegram group. usually scam indications on some projects after the ICO period about 25% of the time remaining. You will see some opinions from bounty participants about the progress of the project.

Telegram is the only source of airdrop that most of them are not legit. Because it is not known who moderated or manager. Just display the registration form and some of their ICO telegram groups that even we do not know who the admin can be responsible for.
More selective is something that must be done to follow airdrop, such as airdrop along with bounty and linking links in bitcointalk forums, so it can be known to the manager and can consider how the quality of the manager in responsible

Yeah, you're right
Now there is too much fraud on ICO, I have followed several telegram groups from ICO investors which they created and named the group as ICO deception victims they follow. As an example : https://t.me/CircleCoalition , https://t.me/denarochat

Even in a night can get a surprise. Often I invest some altcoin for "A" days and on the day of "B" I have been surprised that the price of alt 0.2 rises in price rather than from day A. Is not that a surprise?
It's just a long analysis to get a surprise on the day "B"

You should ask someone skilled in the field.
