as a start this can be a good thing but as long as you don't get sucked in and don't waste all your time on it. just do it enough to get a small amount of moderately free money to start your trading in the altcoin market and then slowly build your capital up after you learned how the altcoin pump and dumps work. after a while you can even invest real money if you became confident enough that you can handle the risks and eventually start making real profit. but as i said if you spend all your time on meaningless jobs like bounties then you will miss out on learning how to trade and will never make any decent amount of money either.

so far the only interest that people have shown in altcoins is as an investment vehicle so even if these companies entered the scene they would not be as successful as most of the altcoins that currently exist because since people want profit they will always go towards the looser coins where they can get manipulated easier and pumped more as the result.
nobody is going to use a centralized facebook coin when some other shitcoin is getting pumped 1000% in one week.

the important thing in my opinion is that the more rises we have the more confidence is going to come back to the market helping with the subsequent rises. for now there are still people have fallen for the FUD thinking we still are in a bear market whereas the actual bear market ended months ago. and as these people slowly wake up and realize their mistakes they start coming back to correct their wrongs and that adds to the already ongoing buy support and pulls the price higher with a stronger force.
the result is that resistances are no longer a matter of concern anymore specially at these low levels at the beginning of the rise.

in my experience you shouldn't hold any of the altcoins under any circumstances because the best case scenario for an altcoin in the long run is that it rises but the rise is not going to ever be as big as bitcoin rise in the long run so in that "best case scenario" you lot a lot of opportunities.

but in 90% of the altcoins you won't get that best case scenario. instead you will get the worst case scenario which is that altcoin loses value and continues going down so every day that you hold it you will lose more and more money.

altcoins are only best for short term trading during their pumps.

"crypto" is not a singular thing to suffer from a singular problem!

there are thousands of them around and each of them have their own issues. most of them however are in fact suffering from inflation mainly because they were created by people who have no understanding of economics and they wanted to make money so they premined a huge amount and dumped it on the market.
many of them also have bad designs like ethereum that has unlimited supply and the inflation is huge causing the price of these coins to continue to drop over the long run.

but none of the altcoins have ever followed bitcoin! all of them got dumped each time bitcoin price went up. the only difference is that when bitcoin rises 10% they do NOT get dumped -10%. instead they get dumped about -8% for example so the result is a 2% rise in their USD value. and since 90% of the market is trading altcoins with bitcoin then that USD value does not matter at all but the BTC value that got dumped is important.

that price number is $50k not $5 million!
it may not be reached this year (only because of the fact that we are reversing the downtrend and it takes a lot of time) but it certainly won't take "8 years" to get there. in 8 years, $50k is going to be a part of history just like $10 is today.

i am 99.9% sure that it is a scam. nobody is going to give you profit for just storing your coins with them! how are they going to gain enough profit to share a big chunk of it with you anyways?
i would suggest staying away from anything like that. there has been lots of cases like this, websites and so called wallets that promised big and small interest amounts to gather some coins and then run away.

check out the mining board, there are good topics there which you can read and gain more information: https://bitcointalk.org/index.php?board=160.0

there are also online "calculators" which you can also use to calculate how much profit you can earn (if any) based on your hardware (hashrate) and electricity cost plus the difficulty of different coins. an example site is this one: https://whattomine.com/

in the end it will come down to your costs and  your choices. for example choosing coins that are getting pumped and mining them to dump at their pump peak is going to be more profitable.
in my opinion it is not worth it to enter mining if you don't have extremely cheap electricity even if you have a medium level cost and can make it profitable.

fee discount makes sense and the exchange would not have to "spend money" but only receive a smaller profit since they would be giving you a small portion of the profit that they would have gotten otherwise.

but the other thing about "deposit bonus" doesn't make sense at all because the exchange has to give you the money out of their pockets and why would they do something like that if they are not shady?!

i would go as far as saying a decent exchange doesn't really need these types of reward incentive to get customers though. but advertisement is always a requirement for any businesses.

how is it that you have a decentralized platform but still you are receiving fees from the user's trades? i can't make sense of how that works in a "decentralized" design. i would appreciate it if you explained it here.

you are facing two big problems without even knowing it. first is the fact that IEOs are just like ICOs and they are risky bets you are making which have a high chance of failure not to mention many of them are purely scams that are robbing you without you noticing until it is too late.
 the second one is that the exchanges are not trusted to begin with. right now the biggest ones that we have like Binance seem trusted but in reality they are not trusted at all. they are on the same path as their previous similar exchanges like Bittrex, Cryptsy, Bitconnect, MtGox,... and they all run away or get hacked eventually. and they all do shady stuff behind the curtains.

i don't know why people still think profit is in investing in these types of projects with a fund raising scheme! even if you look at the whole year of 2017 which was the hottest year for ICOs (it doesn't get any bigger than that) you can see that the profit of ICOs that got pumped big time is still tiny in comparison to the good old altcoin pumps that we had. in other words the smallest altcoin pump has been so much bigger than the pump of an ICO!
now that ICOs are dead, that profit is also nearly dead. so seeking it out now is just the worst decision anybody can make in this market.

since staking is equal to me bag holding that altcoin to gain a profit in that altcoin and this act is extremely risky in altcoin market, i would never do something like that and i have not done it yet. for profit i always prefer trading the pumping coins.

also:
that alone is a reason for NOT doing that because to put simply whenever any coin is giving away "free coins" at ridiculously high amounts without regarding inflation and the circulation of easily gained coins in the market, it is a 100% guarantee of that coin's price drop.

to be honest i don't see any difference in XRP that is new! it has been having the same trends as it always had for as long as it existed. the same pump and dump and death until next pump trinity!
every now and then the team pumps it hard by spending a lot of money on the market and on the internet hyping their useless centralized token and each time that pump lasts a short time, then as it reaches the maximum they dump it slowly to take out their money and make a ton of profit. then the coin enters its death mode which is what we are seeing now. and it will last until they pump it again.

anybody who is "impatient" or "disappointed",... have been doing it wrong! they shouldn't have been bag holding in first place.

if you have really learned to not bag hold altcoins and sell them at the right time before their dumps begin then you are already better than 70% of those who are participating in the altcoin trading every day! because most of them are small time traders who buy some altcoins and think if they bag hold them then they can make a lot of profit from doing so but they end up being dumped on and lost a big part of their investment and go away for good.

actually technology is the only thing that matters! and using PoW or even having high hashrate doesn't matter at all. you can take a look at hundreds of shitcoins that are both using the PoW algorithm and have a high hashrate but they are still shitcoins and completely useless on the way to altcoin graveyard!

your question and your title are unclear.
do you mean buying domain names that are related to decentralization and blockchain? (like buying bitcoin.com for example)
or do you actually mean some sort of decentralized domain registry, meaning something like NameCoin was doing which is decentralized itself?

actually IEOs are worst than ICOs because of 3 main reasons:
1. they are still doing the same exact scam but now they seem legitimate only because the name is different and an exchange is backing them.
2. they are already listed on exchanges so the dumping is going to be faster and bigger since you don't have to wait around and slowly see different people come by and dump the token. everyone has a deadline and dumps at the same time.
3. it is giving exchanges too much power and they will surely abuse it if they aren't already.

you have to start having realistic expectations out of the market and the "signals" that you are looking for if you want to actually see any signal before it is already too late. so far a couple of months ago we reached the absolute bottom where all the manipulation and dumps could not break it any lower anymore and from then we have seen a 78% price rise and that is your realistic "string trend reversal signal" which has shown itself and those who are experienced in the market have seen it and have been buying bitcoin more and more specially when we have a dip (correction) like today.
