bitcoin is not Ideal, it represents possibilities.

[Doofus]

Three years ago or two years ago, if you asked me what Bitcoin is, I’d tell you it is the future of money. It is managed by the network, not by the government. Plus, it is private, anonymous and fast. It’s just perfect!
And Bitcoin is proved very successful. But it has inherent risks like anonymity, hacking，51%attack, double spending. Stop imagining bitcoin is perfect. No coins are perfect. I’d say bitcoin means more about possibilities, possibilities of expression of value. Before, I’ve been taken it for granted that the government should control currencies. But now I’d like to take a moment to think of the question:
“What is the nature and origin of money?”
by hacked, i only mean btc exchanges and by 51% Attack, i mean hash power is seen as by many the king in the btc world; and by security, Large Bitcoin Collider is working to smash open btc wallets. http://news.8btc.com/bitcoin-is-not-ideal-it-is-an-expression-of-value

Bitcoin can't be hacked, it's impossible.  Even 51% attacks wouldn't be hacks, they'd just be attacks on transactions.  Double spending isn't really very much of a threat unless it has no confirmations - a lot of the reason we have mining is to fix the double spend problem.

A lot of the problems you mention don't exist.  Anonymity isn't even a problem, and if people want anonymity they'll gradually move to real anonymous coins like Monero, and illegal activity will just be a side effect so it doesn't really matter that they're used for illegal activity.  Cash is as well.

Bitcoin isn't perfect but you're looking at the wrong things as problems.

You may have many questions on Bitcoin features and drawbacks. Well, everything in this mighty world has drawbacks. This is the basis of evolution. Same applies to Bitcoin and one of the major reason why we see more and more cryptocurrencies everyday is the lacks of Bitcoin. Just take a moment and go through Altcoins ANN section, you will see many coins claiming themselves to be superior than Bitcoin on these basis.

Bitcoin can be hack? Impossible.
I guess your were talking about the bitcoin exchanger sites that got hack? Right.
51 percent attack is just spamming the network with transactions but the solution is miners. Double spending the solution is also miners.
Bitcoin's only major crisis right now is it's stagnant scaling problem.

Where are the real life cases of double spending?

The world is going towards IoTs (internet of things). Everything will be connected in future. The missing part is money. Although online bank transactions and credit card payments contribute to the online concept, but still there is a need of a strong cryptocurrency to become a Pivot point in IoTs. So far, Bitcoin is a strong candidate, but I agree there are a lot of problems regarding the security of something which is online... Special protocols are required to safeguard Bitcoins from adversaries.

I stopped reading after you said bitcoins are anonymous. Obviously if you present false information in your  statement your whole post is going to be stupid bullshit FUD.

TD;DR, OP is going to use shitcoins for his big important purchases now. Thanks for dropping by. Don't let the door hit you on the way out.

A bit of rephrasing would make it easily correct - "Bitcoin can be solely pseudonymous, making it anonymous for practical purposes as long as you take various steps involving anonymising your own Internet connection and using mixing services, or at least dramatically closer to anonymous than digital fiat currency as long as you're careful enough". 

But that doesn't sound so nice in a post like this, so why be pedantic?

Yes,the problems you mentioned are not at all an issue.Bitcoin cannot be hacked at any time.I do accept that bitcoin is not perfect.But i could surely say that bitcoin is far better than the existing centralized currencies.

by anonymity, i only mean that's the first impression of bitcoin to many people. of course, the pseudonymous is more accurate.

where bitcoin is anonymous if you don''t reveal your name attached to your address, which is the same as any other coins, otherwise you have a different definition of anonymous here

in fact the possibility to track each address don't make bitcoin not anonymous...

this is one https://bitcointalk.org/index.php?topic=152348.0 and i remember at least another but i can't find it at the moment

after 3 or so years I am still saying a similar thing, although I never used the word "anonymous" I prefer calling it "giving you a better privacy if you know how to" and I would never call it perfect but only because NOTHING is perfect. but bitcoin is the best thing that I have seen so far. many others claim to be better, some even come close but nothing could compete with bitcoin so far.

But it has inherent risks like anonymity,

what is "risk like anonymity" how can it be a risk?

hacking，

bitcoin has never been hacked and for many years to come, it can not be hacked. the cryptography level that it uses is good enough to prevent it and in case some vulnerability was found it will affect a lot of things, not just bitcoin. and it can be patched.
hacks have always happened because of people's mistakes. like having a key logger, having no password on your wallet, not using cold storage,...

51%attack, double spending.

I wouldn't call these as "risks". these are small possibilities that also can be prevented.

Stop imagining bitcoin is perfect. No coins are perfect.

it is best to have a better understanding of the advantages and disadvantages (or if you like calling it risks) of bitcoin or anything for that matter before starting to use it and try to learn then from reliable resources not what you read on the internet from random source or what your personal understanding is. they can be very wrong.

Looks like you have just woke from a long nap, I really don't know which year you are exactly trying to draw attention to. As far the attacks Bitcoins is unhackackble, if you are trying to say exchanges were attacked then those exchanges of course are not fool proof, it's been said again and again not to trust them. No Bitcoin has ever been hacked. Wake up, read around the forum you may wish to change your words.

[Sniper44]

bitcoin is the first of its kind (at least the first one that became big and popular on a large scale). and it has also been receiving improvements, bug fixes, etc. so it is understandable that it is not perfect. there are always weaknesses in every system and anything that claims to have none is clearly lying.
however i'd say these weaknesses are not at all serious or a reason to call bitcoin "not perfect".

[mobnepal]

Anonymity => is actually a feature not a problem, why anybody have to shout out about their financial transaction.

Hacking => Bitcoin is not vulnerable to hacking, if private key is placed in secure place.

51% attack => Bitcoin network is no more vulnerable to 51% attack because it is almost impossible for someone to spend a lot of mining power to attack bitcoin network these days.

Double spending => Double spending is possible, but after getting one confirmation merchants don't have to worry about double spending.

Well, i like your opinion on bitcoin its really good but bitcoin is the one who helped me with my expenses in the house by earning it and also their are alot of hacks and attacks but you got to be careful on it be secure by using a secure wallet i know bitcoins isn't that perfect but almost countries in the world who use bitcoin and bitcoin is money in the internet so its perfect to me.. the nature of bitcoin is to help those people who want's to earn and buy stuff on the internet origin of the money is to make life easier and fair.

Recently, a group called the Large Bitcoin Collider(LBC) claims that it is using its computing power to smash open bitcoin wallets owned by other people and potentially taking the coins inside.http://news.8btc.com/bitcoin-is-not-ideal-it-is-an-expression-of-value
That explains how bitcoin's privacy is widely misunderstood.

you do know that project was a rootkit to abuse the trust of fools who run that so called collider on their computer, right?

also i should add that they never "smash open" anything apart from some private keys that were put there to be found as a puzzle project.

Even in science there is no such thing as ideal, ideal gas, ideal number, ideal transformer, ideal conditions, because these things are supposed to be perfect but there's always have a flaws and I think that's okie.

These ideal things had bring us to this point. It serves as an outstanding peak that need to be reach in order for the system to be perfect. Bitcoin is not ideal of course there's always flaws and errors. But the possibilities it can bring brought us hope to change the monetary system. The possibilities are endless so they say and it will keep improving.😇

Bitcoin is far from ideal, otherwise it would have been adopted at the onset. But in this world, nothing is perfect. Bitcoin is better than fiat (which is also flawed) in some aspects but it has also its own set of deficiencies. We are going to witness continuous changes in our currency system and bitcoin will be one of the players in a world that's heading into a more digital future.
