What is your biggest concern with Bitcoin right now?

[tyz]

in the short term it is definetly scaling of Bitcoin when i comes to mainstream. long term there a thread of quantum computers in my opinion.

[Amph]

my concern is that adoption may take a long time, so long that something better might replace it, or government might find a way to fool average joe into something akin to bitcoin but that is centralized

basically i'm worried that bitcoin will remain only a niche thing...

I am personally concerned that it will jump through the roof and I will not have enough purchased so that I can ride it up.  I think that this time when Bitcoin jumps in price, it will make a few millionaires.  I want to be one of those people, I just do not have enough at this time to make a dent in my goal if it jumps right now.

My first concern about bitcoin right now is that I have not never enough money (as I want to have) to buy bitcoin as much as I want. Then the second one the lack of velocity in its spread. Even the transactions with bitcoin were doubled the year just leaved compared to the previous one yet me seems that the are few who "play" with it or at least not as much as needed in order that we can see that all we want to see. Its value and price at higher levels, more stability of the lasts values and massive use of it everywhere.

Security and the probability of scamming. One has to be pretty tech-savvy and certainly not letting his or her guard down in order to avoid getting scammed or losing coins (I assume accidents like this can be minimalized but never banned completely). I haven't been on this forum much the last week, but I notice there's a serious incident going on right now regarding security and scamming. Infrastructure of BTC has to mature much more and made somewhat fool-proof before crypto really can take off and gain a strong foothold in the financial world. Now, I'm not experienced regarding crypto so I might be talking complete BS here.

Haha i came here wondering what this was about and I actually have the exact same concern. I wish I could make some more before the halving. I'm hoping to make some spending money to suprise my fiance with and not planning to hold bitcoin for the long term but plan to continue to invest in bitcoin but not planning to hold it. Just hope it's able to keep up with its increasing popularity.

Having so many scammers makes me worried.

Why would people buy bitcoin if they know so many people are willing to scam them.

Even worse if so many people use it for illegal things...

My friends always laugh at me because bitcoins is a criminals paradise.
Since i am a very sensitive and silent guy they tell me there is no place for me in bitcoin or using bitcoin.

long term there a thread of quantum computers in my opinion.

Do you seriously worry about this?  I worry about this just about as much as I worry about being struck by lightning - twice in the same day.

Quantum computers do not exist.
Quantum computers with enough power to actually do something interesting will not exist for a long time.
Even if they existed, with enough power, Bitcoin is basically immune to quantum computers.
Even if they existed, with enough power, and new algorithms were designed to make them a threat:  all users could simply stop reusing addresses making it impossible for anyone with a quantum computer to make a profit from the blockchain.

Even after all that the Bitcoin protocol could be changed as needed to avert any possible quantum computer attack.

I worry about the US dollar and all other currencies because:

Having so many scammers makes me worried.

Why would people buy bitcoin use dollars if they know so many people are willing to scam them.

Even worse if so many people use it dollars for illegal things...

People use all sorts of things for illegal activities it doesn't make those things bad. People make things bad. With that said people run all sorts of scams every day. Look at used car salesmen. As more and more people are introduced to bitcoin the more secure they will become

[Mr. Forum]

My concern today is not even that the bitcoin is not growing. It is very true that the bitcoin trading is growing on a daily process. However the concern I have today is the governing body behind he bitcoins. Just like any currency, when bitcoin is not regulated, it will be misused and people will mine as much as they can. At the end of the day, it will result to s situation where bitcoin is never valued as it were before.

[BurtW]

people will mine as much as they can.

You do not know how mining works, do you?

The more people mining the harder it gets so, on average, the number of Bitcoins mined is very well controlled no matter how much effort is put into mining.

Currently 25 Bitcoins are mined about every 10 minutes - that cannot be changed and does not change, no matter what the people do.

My biggest concern with bitcoin right now is the scams associated with it. It was difficult to trade with bitcoins on-line without a trusted mediator but even that is out of the question now because no one can be trusted. So if one wants to work on-line or do any sort of trades they have to take the risk of either getting scammed by the person they're dealing with or the mediator.

I can see now why some people stay away from using bitcoins. Anonymity has its advantages and disadvantages.

That is also my concern I really like to hoard as many bitcoin as I can as this is a very promising year for bitcoin I would like to have at least 5 bitcoins when it happen right now I am doing signature campaign,faucets and investing on cloud mining but I Guess the best way to get more bitcoins is to but while it is low at this point of time

This is a lot of peoples concern. Just try and buy, and earn, as many Bitcoins as you can before halving comes. When halving comes, that is when the price will go through the roof. There is still around half a year before that, so there is really nothing to be worried about. All the millionaires that invested huge amounts into Bitcoin will be billionaires after halving.

[owm123]

Mine concern is rise of bitcoin blockchain forensic and analytic companies that can analyse bitcoins movement in the network, due to bitcoin being pseudo-anonymous and not fully fungible.  I'm scared one day when I will want to use my bitcoins, I will get a message that some mine bitcoins are tainted or were used for something illegal, and will have no or lesser value.

I'm scored more issues like this one for example:

I was afraid that if people are getting bored with bitcoin and make price drops
