There are numerous reasons.

Earned the btc, bought the btc, won the btc it is just like with fiat some have a lot and some not.

you are asking a general question then limiting it to one specific case.

i will first say generally, that people buy bitcoin and invest in it. many have been doing this for years, when price was so low. some when price was $10 or less some like me from when price was $200-$400
30BTC were worth $300 and $6000 respectively at those prices.

or it can be services, such as a mining pool, an exchange cold storage, a web wallet service,... these have thousands of bitcoin at their disposal.

now your specific case, when you see someone (an account) on a gambling site with lots of bitcoin on it there are only two assumptions in my opinion
1. it is millionaire kiddo with lots of daddy's money who is wasting it on gambling
2. the site is reporting fake numbers.

They early bought when worth cents or they just bought like 5k in bitcoin.

How people can have so much bitcoins in ther wallet? Because they can afford to buy ihuge amount of bitcoins. Most of bitcoin users are usually gamblers. I think thats normal to see huge amount of btc on their wallet. These gamblers are crazy.  Some of them are just early adopters who bought huge amount when the price is small. People can have much bitcoin in their wallet. As long as they can afford it.

It's not strange's,like normal at all.One most commonly consideration,may be early adopter actually when bitcoin price was low,and now possibility they were Millionaire.Can be professional Miners,involved with bitcoin hardly,gamblers,pretty good trading skills etc usual requirements that you expect from such of those people,or they should have.

if they have a lot of bitcoin it means they did a lot of works or bought them. only with gambling it is impossible to earn 10 to 30 BTC. some people may earn but they'll loose them again because they are addicted gamblers..
if you want to be on that list you need to work so hard.

Haha. Don't we all? 

Anyhow, owning 10's of bitcoin is not totally impossible for you, me, and everyone else.
The magic ingredient? Work, work, and work. 
Work (sig campaigns+article writing+offer services in-forum) then save everything earned for future capital and investments.)(Or simply hold, long-term)
Then, you work your ass off and learn trading and investments.
Forget about gambling, that's a money drain. (If you're too attached to casinos, then put your money with the house instead)

It's normal , how people have so much money in their banks account ? If you find someone who have too much coins then he is probably an early adopter (when bitcoin was worth a few cents/dollars) or he is an investor who decided to buy shitload of bitcoin and hold for long term and usually , people don't take such a risk on gambling because they know the risks involved.

Or those people earned the bitcoin they have.
I don't have a lot of bitcoin too. Those people just earned them bitcoins like how i did by investing to some ICOs which took time. 30 BTC is a lot, not sure if I can earn that much later with signature campaign but I a better start now than just reading all the information here.


You too can do it by trading and joining campaigns.

The early adopters usually have hundreds, if not thousands of coins on their wallets. (that is, if they still have their coins.)

Another possibility is the serious investors. They use their fiat capital to buy and hold. Usually for the long term.
Or it could also be the active traders.

As for gamblers, I say that the majority have less than 1 bitcoin in their wallets while the high rollers could have 10's of bitcoins.
Those coins are usually bought.

10-30BTC doesn't count as much for early bitcoin adopters and for hardcore gamblers. When price used to be few $ per bitcoin, many early adopters bought 1000's of bitcoin with high speculation, still few of them have 1000's even 100k bitcoin in their wallet so it is normal to see people with high bitcoin balance. But storing large number of bitcoin in web wallet or gambling wallet is not advised.

They are magicians, they can use magic spells to have as many bitcoins as they want, you can do it as well, I'll give you the ingredients:
Bitcoin core wallet installed, or you can register in a mining pool.
Buy a few antminer S9, plug them in and start mining.
