What do you think is the biggest disadvantage of bitcoin?

[kolbalish]

As all know, the disadvantages of Bitcoin are highly paid fees, late confirmation, unsecure main systems, highly volatile, compared by many, etc. Having that it is the number one digital currency but offline it has a more complex situation. In my sense, the most important disadvantage is scams in BTC.

 One of the biggest disadvantage of bitcoin is, know the time to sell or buy in the market. I find it difficult to understand when and where to sell my coins that will enable me to make a good profit in the market. Many people have lose their profit base on, they buy when they suppose sell in the market.
When you buy when the price of bitcoin is low and wait for the market to go up so that you can sell and make a good profit.

micro-transactions are not suitable for bitcoin. like you said, we could pay more fees with a longer confirmation time just to make a small transaction.
however, big transactions could get benefits from bitcoin. you can read it on this forum, a month ago there is a thread about a huge bitcoin transaction. the sender only pays $3.54 for the fee. a big and cross-border transaction surely gets the benefit from bitcoin. https://bitcointalk.org/index.php?topic=5285199.0

meanwhile, I used my debit card a few days ago to buy computer stuff, it charged me 1% 
it's a cross-bank local transaction.

The decentralization should be an advantage but the space is actually controlled by some people. It is difficult to deny the manipulation of price and the process of hoarding. Bitcoin cant be the king in the space for ever and the whales will become threat in the space in the future. A million bitcoin holder can easily manipulate the market that holds trillions of dollar that is in the world economy, it could be threatening to government and world leaders.

I agree with you, that it is difficult to avoid market manipulation for crypto users.  But I understand how the whales control the market, and there are a few tricks to avoid the whales' manipulation of the market. 
1. Do not often monitor the order book.  The less that depends on measuring the depth of the order book, the better.  Most exchanges allow traders to minimize the order book from the trading screen display.
 2. ignore large individual trades and focus on longer price trends to avoid confusion to avoid wash trading. 
3. avoid detection when whales prop up prices to liquidate their exposure by taking a long-term look at crypto price action.

But there are times that the mempool is not busy. However, if this will be used for payment method, I don't think people will want to wait for the time that they can pay low fee for their transaction. So for me, the biggest disadvantage is the fee when it comes to payment options and the time of confirmation. But for remittance purposes, btc has advantage as you will pay relatively low fee at a faster time as compared to big remittance companies like WU.

Disadvantage are the resources to be use like internet connection, devices to store the files to access the bitcoin in the blockchain, the keys that you can't remember due to long characters being used,  the possible hacking activity by hackers, scammers, fraudsters and phishers. All of this are disadvantagr but we can say that all can be prevented and we know also that bitcoin is a  secured system.

In my opinion, the main disadvantage of Bitcoin is the centralization of its mining. 

At the same time, there is both monopolization of the production of mining equipment and monopolization of the hash rate.  Currently, the main manufacturer of mining equipment is Bitmain.  If everyone on the planet had the opportunity to participate in bitcoin mining, bitcoin would be more decentralized.  Currently, many people are not involved in the mining of bitcoins and in the process of maintaining the network of the first cryptocurrency. 

Many people see Bitcoin solely as a speculation tool.  Bitcoin lacks ideological supporters involved in the industry.

I don't believe that this is a disadvantage. At least not on bitcoin itself. My question goes on what bitcoin can't provide to its users.

Disadvantage are the resources to be use like internet connection, devices to store the files to access the bitcoin in the blockchain, the keys that you can't remember due to long characters being used

That's why we use a seed, for 2 main reasons.
1) Less characters to remember/write down.
2) Access to unlimited addresses, instead of one.

If everyone on the planet had the opportunity to participate in bitcoin mining, bitcoin would be more decentralized.

That's true, but as long as no one touches the 51% of CPU power, it remains purely secure. As for the decentralization, it will always be. Mining doesn't make it more centralized.

I personally feel that utilizing illicit bitcoin is a major weakness and that is the motivation behind why numerous nations don't acknowledge it.
At the point when we send money to somebody for criminal operations, the bank makes a move promptly and capture you.
The reality is the bank has the capacity to follow fiat exchange and know where our cash goes.
Lawbreakers are very much aware of it and they utilize bitcoin so banks can not way to deal with it. Else I never observe bitcoins has any detriment.

The problem with this argument is that this makes it seem as if it is impossible to commit any kind of crime with fiat currencies, and even if we exclude cash which is completely anonymous and cannot be controlled we know that many financial institutions are at the service of criminals and corrupt politicians and despite having the opportunity to stop large operations that they know are completely illegal they decide to allow them so this argument holds no ground in my opinion.

Its obviously for me the transaction cost. If i send 0.001 btc than sending fees 0.0005-8  as well as if i send 0.1 btc transaction fees are remaining same. Its too hard to believe sometime if u send 7$ in btc fee is 6$.

[Xxmodded]

The biggest disadvantage of bitcoin is still illegal payment transaction when we got problem with sending or our wallet stole by the other we can process to the law because not get legal as currency payment transaction and bitcoin not available for investing. During bitcoin keep safety for saving and holding maybe we not afraid for hold bitcoin in long term, but when get problem we can't know what have to do if our bitcoin fund is gone. Maybe when bitcoin have been legal payment transaction many people will use and invest on bitcoin because anything get legal will give positive and any respond from many investors.

Talking about the word "Biggest Disadvantage" is not appropriate because if there is some things that is not serving us from Bitcoin it cannot be that big.

of course first the volatility in which many has been asking why need this to happen not knowing that with this we can generate or lose money.

Why irreversible but this is one of the safest way to generate transactions.

Its obviously for me the transaction cost. If i send 0.001 btc than sending fees 0.0005-8  as well as if i send 0.1 btc transaction fees are remaining same. Its too hard to believe sometime if u send 7$ in btc fee is 6$.

This is not permanent because it change from time to time and we also have option how much to use.

These are not really the disadvantages because internet is free and no resources has been used extra, and if bitcoin become main payment medium then we don't need banks which means we can save lot of work force, electricity,tax money to pay the employee and all other expenses so we are going to save more than 90% actually.

It's not really difficult to believe and in fact we see many situations like this happening especially when the network is very busy and while this may seem to be odd at the same time it is just part of the nature of bitcoin, and while that may seem to be a disadvantage when it comes to sending large amounts of money bitcoin is way cheaper than any other method which is one of the reasons that we are seeing that institutional investors are getting really interested in this market.

The biggest disadvantages of Bitcoin are high transfer fees, transfer speed and volatility. Unfortunately, all three features do not help Bitcoin to be a good exchange tool.

[angrynerd88]

The main impediment I taken note on bitcoin is pump and dump. Numerous dealer will be active with their exchanging trusting that the cost has expanded for them to supply to advertise but the thing is to see the cost has drop down. No speculators will be cheerful, see advertise diminish since of a few coins they are holding for a long time. Few weeks back bitcoin pump exceptionally well, that make a few financial specialists have trust that it'll still go higher some time recently they can offer within the showcase.

[jerrison]

The biggest disadvantage of bitcoin is its volatility its a YO-YO it exist in a volatile market which susceptible to losses the losses can be incured when the prices plunges or drops when market forces comes to play and the HOLDER has no infulence over the prices it becomes a disadvantage

[Rebdoomer]

The disadvantage of Bitcoin is when people who get hacked and get their Bitcoins stolen. There's no refund system for that.

I remember back then when I was just trying to send a half a thousand worth in USD of Bitcoin and the miners fee that time was double the amount of what I send.
Not sure if the online wallet that I am using is just trying to screw with my money or something but that was just absurd of an amount.

[Kong Hey Pakboy]

From my perspective, the biggest disadvantage of bitcoin is the transfer speed and high transaction fees because many bitcoin users are having trouble making transactions with this kind of issue. Many people hate the bitcoin volatility, but for me, bitcoin's volatility can both be a good and bad thing for our investment; it only depends on us on how we will handle our investment.
