Tron is among the worst altcoins out there that didn't have any real development or innovation in it but at the same time millionaires behind it that have been hyping the project day and night. they even bought bittorrent brand to use it to advertise their crapcoin. all these news that we see is part of that hype they started and news sites are enjoying anything that is hot no matter if it is negative or positive or even real.

none of them!

altcoins are either suffering from bad supply designs such as having unlimited supplies, very huge supplies that are considered unlimited in practice,... which is sometimes also combined with some shadiness such as premines and ICOs.
or they have no future in first place because they copied some other project (90% of times bitcoin) and messed things up trying to change the variables so they became useless.
as a result they have no long term potential to make them "store of value" unless you are ok with losing a large percentage of your money in the long run.

Grin that you mentioned falls under the first category of having a bad supply distribution/totals design.
Monero can be a good option but that still has some serious scaling issues. but at least it has interesting feature and is actively being developed.
ETH that you also mentioned is not because it falls under the category of unlimited supply and also has the downside of not being immutable.

there is absolutely no difference between rolling 1, 2, 3,... and rolling 0.1, 0.2, 0.3,... as long as the number of possibilities are the same and the house edge is the same and the calculations are the same (no bug like rounding,...). it is like rolling two actual dices one with dots on it (1 dot=1, 2dots=2,...) or write actual numbers on it (1, 2, 3....6) the result is the same.

i also think what veleten said above is false. the multiplier (like 100x) depends on how much the dice  site is flexible on letting its users have a chance of winning big. otherwise you can give the same multipliers on any value range. for example in freebitco.in you can roll whole numbers (from 0 to10000) and the multiplier goes as high as 4750

it is because when you are bombarded by articles about how bitcoin is being used by money launderers many people eventually start believing in it even if it really doesn't happen! it goes so deep that eventually those who started the lie believe it themselves too, which is why all these companies like what OP is talking about are being created to sell their services to those people pretending they are "finding" people and linking their transactions together.

it is not and it is at the same time!
basically when the adoption grows it means the number of all types of users is growing. both those who are in for the decentralization and want to fully benefit from it, and also those that don't get the point of decentralization but at the same time they still want to use bitcoin.
not to mention that many of these users will slowly learn more about bitcoin and migrate to "real bitcoin wallets" and that means Coinbase was a great starting point to introduce bitcoin to a lot of people who want an easy entrance instead of being subjected to a lot of complications on their first day.

i believe your confusion comes from the fact that most people when they call a coin "dead" they don't mean its price falling down to absolute zero. which is probably what you have heard. they said 85% of the altcoins died not just dropped down to zero.
a dead coin is usually a coin that has no usage and no point to exist and has been falling ever since it was created. they usually had a high volume in a couple of days when they were created and then lost it and now have a volume less than 0.01BTC per day and a price less than 1 satoshi.

obviously YOU would prefer that because you are the receiver but the owners would hate it because now they would have to "spend money" whereas before it didn't cost them anything at all. you see when you create a token out of thin air, it doesn't cost you anything since you get the whole 100% of them for free. so paying in those tokens that you created for free is preferable to the token owners which is why they do it in first place. but paying in something else like bitcoin means they have to go spend money and buy bitcoin to be able to pay and that costs so they never do it.

the problem with this market is that it can give a lot of the newcomers a false sense of confidence specially during certain periods of time where it is easy to trade. you just have to close your eyes and select an altcoin to make profit. for example 2017. that year ruined a lot of people and emptied their pockets because they thought they were expert traders just because they made some lucky bets on the market. then when the actual market showed its face and they started losing money by making the same "bets" they slowly realized their "confidence" was a sham.
only those who learn from their mistakes can come back to the market and continue on.

existence of these services which actually make adoption of bitcoin super easy for a lot of people who will never bother with complicated stuff is not such a bad thing in my opinion. and this stat (30 million) is the proof of two things, bitcoin adoption is still growing even with all the drama and FUD and also proves my point about a lot of people who want much easier ways of entering bitcoin.

it is partly because there is no law preventing them from printing any amount they like so they keep on doing it.
but there is also another reason that people overlook and that is "demand". if you look at the altcoin market, it has been growing and more and more people have been demanding fiat markets so that they could trade their shitcoins with something that has a stable value. but since altcoin exchanges want to escape regulations and don't want to add fiat they have been adding stable coins.
tether being the popular one, attracts people.

now considering the fact that when bitcoin falls, altcoins get dumped hard, they always want an stable coin to go to. and that increases the demand for tether and they have to print more of it to be able to answer to that demand.

almost all of those who are gambling with bitcoin are doing it because they can do it without the headaches of KYC and without revealing their identity specially since they could be subjected to hefty taxation in certain jurisdictions under tax laws that want to take a share of your winnings. not to mention that with bitcoin and the fact that it does not have any charge back capabilities there is absolutely no reason for these gambling sites to ask for KYC related documents, they do that in fiat world to protect themselves against those who charge back, use stolen credit cards,... and also to abide by regulatory laws. none of which exist in cryptocurrency world!

and do you have any actual examples of a real organization/sector that has actually adopted this technology and is currently working with it?
because for over 2 years i have been hearing the same exact thing about how different sectors are "improving" by adopting the blockchain technology and whenever i check the "real world" i see nobody even paying any attention to blockchain. and then when i think about it, i see that blockchain is not even going to work in 90% of them.

they ARE cryptocurrencies by definition because the definition of a crypto-currency is a currency that is based on "crypto-graphy", in that definition there is no talk of decentralization. we add that later because the original (biggest) thing we all know is bitcoin and it is decentralized.
the coins such as Libra, XRP, BCH,... are bad because they are centralized and this technology is working best and is desirable as long as it is used decentralized.

you can't just create a new article on your website every time some random altcoin is getting a pump! i have seen your topic in this board that you just create random articles about random coins. you are just lowering the value of your website and now it is considered a clickbait yellow site.
what happens is that pumpers are pumping altcoins every day. but each day it is a new coin instead of repeating it for the same coins because they have thousands of options to choose from and pumping an unpumped coin is always easier.

you are confusing or intentionally misusing a couple of things with each other. there is a difference between media calling bitcoin a bubble, bitcoin being in a bubble from time to time, and altcoins being big bubbles.

media is usually full of shit and is just posting clickbaits and should not be taken seriously.
as for bitcoin, it has bubbles at times and they can not be denied. for example the $20k price  was a big bubble but that doesn't mean you  can call bitcoin itself a "bubble" at any time and expect its price to fall!
and you can't make the same conclusion for altcoins just because bitcoin is not a bubble! that doesn't work like that. every project is stand alone and we have more than 2000 altcoins in existence most of which should not even be alive which means they are in a 100% bubble and need to be destroyed not just dumped! additionally there are a lot of altcoins that are currently worth a lot more than their intrinsic values specially among top 10 altcoins which make them in big bubbles.

2 important things:
- bag holding altcoins is never a good idea
- setting a fixed profit target in each trade and never deviating from that.

of course these two go hand in hand. which means in practice whenever i enter an altcoin, i enter those that are pumping and then i set a profit target for myself to cash out as soon as i hit that target and i always try to stick to it even if i saw the pump going on i still get out to secure my profit.

there is a huge difference between talking about a project which is also called constructively criticizing the project and with spreading FUD and nonsense about that project! the keywords used in that tweet such as "out of thin air", "drug trafficking", and the news in OP "fraud" are pure bullshit. you can't really call it criticism.

no, you first discuss why you think in 10 years a system (quantum computer) that is not capable of producing hashrate and is not even designed for that is going to be able to suddenly produce such an unbelievably huge hashing power that could attack bitcoin!

LOL another delusional newbie who has read some altcoin advertisement online and now thinks he has found some "superior" and "new" technology compared to bitcoin while not knowing that majority of altcoins are exact copies of bitcoin and the things they change always lead to less security and serious flaws in them.

investment-wise, since that is what OP is interested in, NANO is a terrible investment because of its huge supply that has no control and is on the boarder of being unlimited and that gives it such a huge inflation.
not to mention that in all these years that it has existed, it doesn't even have a single real adoption case. how can it be so much better as OP claims and still be useless?

actually the drop in price has nothing to do with size of the amount the dumpers dump on the market. it is all about lack of demand for tokens and altcoins that are useless. so it doesn't matter how much and how you dump the tokens it will crash the market since there is nobody there to buy that token anyways. everyone has just gambled and invested in that token to try their lock in a short term to see how much they can pump it and how much profit they can get. as soon as they feel like the pumping fuel has run out, they make their exit.
