Are  you aware that bitcoin do also have its trading risks? Infact, let's not try to defend bitcoin as Mr perfect asset. Imagine selling your bitcoin to an anonymous buyer on the p2p and also recalling that not all wallet networks requires the validation of KYC during account creation so, such buyer can as well play sellers scam or even the seller can scan the buyer because you has to pay first before coin is released and if you are dealing with a local vendor knowing each other in person, you can  also release the coin even when payment have not been received yet.
Then a meant scammers is liable to also succeed you on trading your bitcoin such being effective with gold which actually has a high level of physical insecurities.

Bitcoin and gold belongs to different types of asset so it's big difference between them, like we can not compare Bitcoin adoption and Internet adoption fairly. Any comparison must be made carefully and neutrally so people who are new won't have misleading information toward Bitcoin like Bitcoin is the best.

Market capitalization of Bitcoin and gold.

More gold will be mined and available in circulation and we can not know the maximum available physical gold in future. With Bitcoin, we know it, there are only 21M bitcoin and it will help its value and price because supply and demand principle.

How is the 21 million bitcoin cap defined and enforced

I don't know about the USA but in the EU there are several online portals where you can easily buy and sell gold. In many of them they don't charge you commission for the shipping from a certain amount or with no minimum amount. For example, in https://www.bullionbypost.eu If you buy a 10 gram gold bar you will be charged about €735 and if you sell it you will be paid €683. It is clear that they have to do business, and the difference between buying and selling is very far from what you say they give you in the pawn shop.

bitcoin and gold are both very valuable asset and then price of the both asset are increase day by day just one is physical and another is virtual. if possible and if you have enough ability then hold both for long time. selling bitcoin or gold are not smart thinking. you can see the past price of bitcoin and gold and the present price of gold and bitcoin. so keep holding bitcoin and gold as much as possible

Where I buy, I'll sell at a price that's not much different from the current purchase price even though I don't make a profit. If I sell gold now at the price I bought it last year, I'm already in a profitable position.
My local country is easy in terms of gold transactions. It just takes time to get to the shop because I don't live in an urban area.

A pawn shop isn't designed as a good place to buy or sell previous stuff. It's more for loans where things are taken as a collateral, the way I see it. But it's a good point that it's easy to figure out how to buy and sell Bitcoin, while selling gold is more complicated. You can try to google and find a place to do that, but there's no system, you might get scammed or just get less money than the nominal market value it. Also, gold has to be physically carried, which is not only uncomfortable but also a potential risk of getting robbed if you just carry it around. So I agree gold is more convenient, although perhaps gold is also safer in terms of price fluctuations.

In terms of value, Bitcoin may be better, but for official recognition of value, gold is the best. In fact, most people seem to make gold as an object of savings. Although its value does not increase more than Bitcoin. If you compare the two, Bitcoin is still very new and young while gold, it has been around since ancient times. This means that Bitcoin is still in the early stages of recognition and still needs time for adoption by the world's people.

If you compare selling gold and selling BTC, of ​​course there are differences and of course everything has the same risks. Yes, the point is that selling gold is of course we have to be able to choose people who bid high for our gold because of course if we are not good at selling gold, of course the profit we get will not be. There could even be big losses and it certainly depends on whether we are clever or not in making gold buying and selling transactions.

and if you think about it, selling bitcoin is an easy way, but what is certain is that in selling btc we also have to be clever in selling because if we sell btc at the wrong time, for example when there is a price drop while we buy btc at a higher price than At the selling price, of course we will incur a loss, so the point is that in this case it depends on our skill in buying and selling transactions btc

Yes, basically I see that BTC and gold certainly contain risks and these two assets certainly have advantages and disadvantages, but what is clear is that selling BTC is an easy way because you just click, but of course you have to know the right time to sell BTC.

Bitcoin and Gold are easy to sell You can sell both of them whenever you want because their is market for it , but Bitcoin seems to be faster in buying and selling because it's value tends to go up faster than gold,and can be kept in a wallet,but gold can't be keep in a wallet and if invested will give you a better return and Bitcoin transaction is digital and being made on a reputable regulated exchanges while gold is physical which poses alot of risk and danger for the trader. In gold, you need to be able to identify the original from the fake and the quality which will determine the selling price .

Yea, I have seen a posts on this forum where a member actually said that it's easy to buy gold in their country but difficult to sell it back to people you bought it from, and in my country, it doesn't work like that. If you actually want to sell your gold piece, it's very easy, and you will also sell it at a good rate if you already know what the current rate is for one troy ounce, but when you don't know about all that, you can be cheated by the buyer. 

Just like a few people have already said, Bitcoin is much easier to keep safely than gold. Most of the time, you can store a very large sum of Bitcoin and no one will know unless you tell people about it, but once you hold that large amount of gold, it could be noticed and can lead to robbery.
