It should not be a surprising thing, seeing investors in such situation. It happens when such investor is still a newbie, who is still learning on how to invest, there is every possibility for him to make mistakes.
Do not look down on yourself when you make such mistake as an investor, because it is a learning process.

Yes, no successful trader will want to divulge all the secrets to his success, because he us riding on other people's shoulders. He might give some tips, just as you have done in the simplest way, but which is not enough to succeed. Therefore, to get more inspired, such person is to look for materials online that can guide in the training and with constant practice, most especially with an amount you can afford to lose and without relenting, you will see yourself becoming a pro in trading not only altcoins, but also bitcoin.

What most of them are after listing is increase in volume traded, particularly on 24 hours basis and by the time they pay hunters, it will appear as a waste of time, because you may not make anything meaningful on it. This is the reason I will prefer new projects.

For your information, ethereum is what is being referred to here and not efirium. Also, any coin can be used for money laundering and that does not make it a scam coin.
Ethereum has been in existence for quite some time now, if it is a scam coin, I believe it would have been dead and it will not be in the second position based on coin ranking.

No wonder there are regulations against crypto in some countries. Although, some have now started embracing it and making good use of the technology in particular, to solve economic problems in their various countries.
Although, at some points you might not be able to separate both, except you are able to totally curb the former.

If he doesn't do anything about it at the right time, a lot of developers will leave ethereum block chain and move to others. It is good we still have good projects on ethereum for now and some are still proposing to come on it, but if you ask other developers that are using other blockchians, they will tell you the one they are on is better than ETH.
This is a call to Buterin to fund the very possible solution to the scalability problem.

This ought to have been known long time ago. Had it been ethereum, being the second in rank is able to outrun bitcoin, then it would not have struggled with XRP like it did sometimes ago. It's competition would have been geared towards bitcoin, but as it is, my expectation is just for it to grow and not to think of replacing bitcoin.

My expectation has always been that bounty managers should always fight for the course bounty hunters, even if the team of the project is planning to cheat bounty hunters, because it happens often. There have been situations where bounty pools were slashed unbearably and delaying payments unnecessarily, yet bounty managers agreed to that singlehandedly, meanwhile, they have received their own full payment. Such attitude should not be condoned.

A lot of investors miss the IEOs on big exchanges, because they are competitive, so they opt for those that are readily available for them, thinking that the story of uptrend will continue. This is one of the factors that discouraged some of them from investing and it seems to have been generalized. Meanwhile, there are still good projects that raise funds through IEO, most especially on good exchanges.

That is usually the situations with runaway or scam projects. Since they have succeeded with their scheme, they then in a bid to close any means of criticism, led to the lock of the thread. I am sure if they have telegram group, it also would have been rendered nonfunctional.

Coming across situations, does not require shying away from them, but to face them squarely and deal with the situation at hand.
Each of the challenges have their specific ways of tackling them. Sometimes it might be wrong to just assume and use the old solutions to solve new problems, which might prove abortive. Rather do your research of the situations and circumstances surrounding it and technically solve it.

Of course yes, you have stated good points, which are typical examples of what is happening to participating in the different forms of campaigns, but I have my reservation on your point number two.
I have seen two different coins listed already, that held campaigns sometimes ago, yet today, they do not have volume as it were. One of them has totally lost its volume and has been delisted on the exchange it was trading the most. That alone is comparable to a scam project.

I checked coinmarketcap and discovered that most of the coins listed are going downtrend. As a matter of fact, they had their all time low this month of August, 2019. For instance, the all time low of mainframe was yesterday 17th August as at the time I making this post. Even if Bit one had seen this coming, it should not be enough reason to delist it.
Why are we even talking about Bitone? Bitone is not listed on CoinMarketCap, therefore, it is not a prominent exchange. There are so many prominent exchanges on which the coins are listed. So delisting then should not mean anything to anyone.

I do not think i have such an ICO at hand and neither have I seen it. Then for such a project to function properly, there might be a problem, because investors could have lost interest in it, if it is taking too much time.
The multiple rounds can be done within a short time frame, that on it's own will make things better.

Depending total on proceeds from cryptocurrency is not a good idea. You should have something else doing, most especially offline, so that you do not end up selling what you should not sell in haste.
You might also be a trader and make more income, but consider the times things might not be as expected.

Trying to create a new DAPP is not the most pressing need. Come to think of it, he already has a project, Tron, whose development has not yet ended, yet he is thinking of something else.
He should better cone of with more bigger and good updates. I expect his coin to also perform so well as BNB.

Some exchanges still have high volume of those coins that have been delisted. Investors and traders might have lost interest in trading such on Poloniex, but does not means there are no other places where the coin cannot be bought or sold.

Till today, many projects are still calling for the services and supports of bounty hunters. Had it been they are not doing the right thing, then a lot of them would have called it quit with bounty hunters.
I still believe that bounty hunters are very useful and their presence is highly needed to keep a project alive.

At first I was thinking of selling all my altcoins and to better hold btc, but after giving it a second thought, I made up my mind to face whatever will happen and of course, I believe that altcoins, most especially the good ones with working products will still grow significant, no matter what might be happening in the cryptoverse.

I sometimes participate in airdrop, but if I find any that asks for KYC, no matter how good it appears, I will not do if.
Back in the days of good airdrops, there was no fear in participating in them, until scammers started taking advantage of it.
