bitcoin problems that need to be solved

[Findingnemo]

#2. non-fungable.  We like to think of bitcoins as being fully fungable.  But the reality is that any bitcoin wallet/coin can be black-listed or otherwise "tainted".  Your wallet could be black listed for any reason, or by mistake with no recourse.  Black-listing means that anybody can create a list containing your wallet address, and then any bitcoins in that address, OR, any bitcoin that ever TOUCHED that address can forever more be treated differently.  If YOU are found to have ever "touched" a black-listed coin, or coin from a black-listed wallet, you could then be targeted, hunted down, your real world accounts/property froze/taken; you arrested, who knows what.  Regardless, not all bitcoins are perceived to be "equal".  And, EVERY bitcoin has a history trail (moving from wallet to wallet) that anybody can easily follow see #1 above.

Bitcoin can never really be great unless every coin is truly fungable.  AND, to be fungable then coins must not be trackable.  Yes, some "alt coins" try to deal with the above.  But ALL mainstream cyrpto currencies especially BITCOIN need to start taking these issues seriously.

Is there a way to make bitcoin non fungible? I don't think so, if you want to erase the history then you should use the coin mixing service so you will be getting bitcoins from some other source but wait why we need to think that bitcoin is always connected with dirty hands? when the adoption comes then everything will change.

I don't think that the problems mentioned by the op are the biggest ones. It's possible to use Bitcoin in secure ways, and as for privacy concerns, I think that if a person is consistently careful, it's impossible to track the owner down to one's real identity (otherwise there wouldn't have been so many scammers whose identities aren't known).
As for #2, I think that Bitcoin is fungible enough, and via things like auctions from the authorities dirty coins can become clean again.
I believe that the biggest problem with Bitcoin is its scalability. With more people starting using Bitcoin and more transactions in the network, the fees are rising and so does the confirmation time. We need viable solutions soon or Bitcoin will be appropriate only for big purchases.

Security is not a problem, the problem is the people that are using bitcoin are lousy in keeping their credentials safe. I don't know what to say about the second part though. In my opinion, the biggest problem that bitcoin needs to solve is the network speed and the transactions speeds.

As far as I think big problems Bitcoin needs to solve that:
_ Propagating knowledge about Bitcoin for users. In fact, very few people know about Bitcoin, they are concerned when using Bitcoin. Bitcoin is not widely used in underdeveloped countries.
_ Need some solution to help Bitcoin market more stable. Prices fluctuating Bitcoin increased continuously, causing new people to enter a fear.

I think it looks like Bitcoin has no problems, Bitcoin is a decentralized peer-to-peer network. No single institution or person controls it. For security, Bitcoin is stored using public and private "keys," which are long strings of numbers and letters linked via the encryption algorithm the mathematics used to create them.
The address listed in the transaction history is normal, we can see from whom and to whom we transact. If an account is hacked, we can see where our assets are going. What I think if it must be fixed is the level of transaction speed and shipping costs.

Compared to recent years the number of people who accept and used bitcoin has grown significantly and in the next few years, it is expected to increase. The number of people who are getting curiosity out of bitcoin is starting to grow, Influencers like NasDaily has tackled bitcoin as a topic a few times.

High volatility is one of the characteristics of bitcoin, So why would you think that it is the problem? Fill yourself a proper knowledge about bitcoin to avoid FOMO.

I think the above flaws are a feature of Bitcoin and it is a good advantage. Take a look at anonymous cryptocurrencies like Monero, Dash, Deeponion all of them are completely anonymous. It's a real double-edged sword. If you have money stolen, you will never be able to trace it because of their absolute anonymity. And for that reason, anonymity is much more banned than Bitcoin.
Bitcoin's problem right now is scalability and transaction speed. There have been many different versions of Bitcoin through many upgrades such as BCH, BTCSV, and BTCD, but currently only Bitcoin is recognized as the highest value.

[Ucy]

If you don't want the content of your wallet to be seen by people you could give them new addresses. The Bitcoin Anonymity feature makes it hard for the public to link the account/wallet to your name.
  By the way, it's better to have my accounts opened to  the public to watch than few privileged people accessing/watching my bank account secretly and without my permission.
Maybe we will have a feature in the future that makes it possible for individuals to cloak/hide the amount of money in their accounts, but the account will still publicly show that something/money is the wallet(but hidden). The only thing that could be visible are transactions from/to the owner's account and the amounts involved in the transactions. But if the transactions and transaction amounts are hidden then their immutablity will need to be guaranteed, so that security agencies and things like that can always go through the transaction records incase something happens .

In regards to the Blacklisting, that must be done with proofs of crime committed attached to owner's coins otherwise they could be considered mere allegations . By the way, it's better to have Decentralized, Public and Transparent communities/groups be assigned the responsibility of allowing or removing such tags on blacklisted coins

There is a limited supply of Bitcoins, meaning there is a cap on the number that will ever be released. Only 21 million can ever be mined, and there are currently 18 million in circulation. As with all free markets that fluctuate according to supply and demand, increasing demand for an item that is in limited supply will push up the unit price.

Mate security is problem, some certain problems we are having today because of scamming is lack of security, people misplacing their account today, it's because of lacks of security, hijacking of emails and wallet's it's because of lack of security, so the number one thing we have to understand and secure very well is things we values, insecurity make people to lose everything they have obtain in life, and secondly if your conscious will you know that its insecurity that makes network to have issues, because  penetrate into network in order to make network inactive.lastly security is the major to secure everything related to cryptocurrency, even life's and properties.

#1. security.  

Depending on the point of discussion, Bitcoin network is secured.  If you are worrying about your personal security then it has nothing to do about BTC network.

#2. non-fungable.  

I wonder how you define fungibility, but from the definition on the internet,

fun·gi·ble
/ˈfənjəbəl/
Learn to pronounce
adjectiveLAW
(of goods contracted for without an individual specimen being specified) able to replace or be replaced by another identical item; mutually interchangeable.
"it is by no means the world's only fungible commodity"

It clearly stated that Bitcoin falls to this category.  1 bitcoin can be replaced by another 1 bitcoin without losing its value.  If you have problem with exchanges blocking your account then you better not do any illegal activity and be aware that exchanges is not a part of Bitcoin network, they are just a third party company that take advantage of Bitcoin popularity.

Bitcoin can never really be great unless every coin is truly fungable.  AND, to be fungable then coins must not be trackable.  Yes, some "alt coins" try to deal with the above.  But ALL mainstream cyrpto currencies especially BITCOIN need to start taking these issues seriously.

It looks like you are being confused on what fungible means..  specimen in the definition of fungible in the term quoted above does not mean the user but rather the item being used and that is Bitcoin.

#1. security; the problem I suggest isn't security with the bitcoin network.  It's YOUR security.  Real world bad guys can see YOUR bitcoin balance worthy of their efforts; starts cutting off your fingers and flesh until you transfer your funds.  You didn't need those arms nor legs anyway.  We'll call you Stumpy.  CURRENTLY in the real world; why aren't you walking around the streets with wads of money hanging out your pockets?  This is exactly what you are doing with bitcoin.  Once you are personally connected to a wallet (all it takes is one stupid mistake), there is no safe/secure way to completely hide again.  I think you an idiot if you believe you can receive/send payments without anybody knowing who you are.  Anonymous payments in and out?  Really?  Real world doesn't work that way.  Even criminals can't pull that off.  YOU are not good enough to never make a mistake.

#2. fungible. I deem you an idiot if you think bitcoin is really fungible.  The CURRENT network mostly treats bitcoin as  fungible.  But this is changing, and, "tainted" coins and wallets in the future will be treated differently, especially at OFF-RAMPS.  Example; you being a naive idiot thinking your bitcoins are fully fungible; you then pay them to somebody and they are CONFISCATED.  Ha ha, jokes on you.  I'm sure there will be plenty of good excuses for confiscating your coins.  You never really know if your coins will be confiscated until AFTER you send them.

I'm hoping somebody makes a bitcoin PRIVACY hard fork; sooner than later.  Afterward, the market will figure out the rest.

Well, that’s why we have pros and cons, everything has two sides to it and this is what you get with having a decentralized currency, that’s the advantage that fiat has over bitcoin. But most times, I don’t see no wrong in how Bitcoin and the blockchain are built and made to be open to the public, sometimes you can see the importance of all that, and sometimes you feel it is wrong.

But, there are ways you can avoid things like this and one of the ways that people does that is by generating new addresses every time they want to make a transactions, but this can be hard thing for anyone to do especially when they have huge amount of money to manage.

[Ebede]

I don't know much about that but trying to know. From all of your comments I can know many important problems and how they can be solved?

Mate we are here to learn and also ensure that we pass the knowledge we grabbed to another person, so the content of these work is Bitcoin problems have to be solve, so our question should be what are the challenges of bitcoin so that we can know the specific place to be tackle before solving the problem, in general what kind of problem does Bitcoin facing, because from news no challenges for now except the fees of some cryptocurrency which are extremely high such as ethereum, Bitcoin, and ripple, so if challenges of settling the problem is the problem Bitcoin had, I don't think its something that can be handle easily.

[acosimo]

Bitcoin has lost it's purpose. Doge is a new store of value.

[CarnagexD]

I don't think security is a problem with bitcoin, since what the people just see is your address and the denominations you have sent, it is up to you to be more mindful of your coins, to make sure that you are not being hacked. Personally I think bitcoin's lack of feature to support its scalability is the main problem, we have here a very promising coin with no proper foundation to carry it when it becomes very valuable, that's why us users are the ones who have to shoulder the problem through  lengthy transactions and high transfer fees.

[BuNga_cute]

I feel the most crucial problem that must be solved is related to Bitcoin transaction fees which are quite high, and also the speed of Bitcoin
transactions which is sometimes quite long too. Indeed, there is already a Lighting Network for this problem, but it has not worked optimally
and is still too complicated for some people to do. So hopefully we can find another solution soon, then regarding security issues, I think
it depends on the user. If the user is always careful about storing Bitcoin and uses security features, there shouldn't be a problem with
Bitcoin security.

[cydrix]

Security is not a problem, the problem is the people that are using bitcoin are lousy in keeping their credentials safe. I don't know what to say about the second part though. In my opinion, the biggest problem that bitcoin needs to solve is the network speed and the transactions speeds.

The problem for the transaction speed is that no one actually runs bitcoin with lots of server to run it there a lot of people though that spends lots of money to buy rigs for mining bitcoin. Security of bitcoin is excellent period.

No one is forcing you to use Bitcoin, if you hate it then get done with it,  off you go without looking back or being concern with it.  If you wanted anonymity you can use privacy coins which is already established.  Why bother make another privacy coins and saturate the market.  At the end of the day, I bet you won't be affected if the BTC market crash due to it not being anonymous  .

[andthereyou]

I don't think it's a problem. I think you are the problem. Why not used other cryptocurrency focus on what you have described.

[protocon]

about the first issue, that's why they have private and public key pair. It has irreversible feature, so it's hard to find out someone's private key even if you know his/her public key. I don't really see any security issues on that part yet but it's just my opinion but good point to talk about
