yes you can.

If it is a high amount, I can give it to you in cash.

how many whales are trading in the last 24 hours from analyzing the blockchain?

In other words, how many whale active addresses are there?

Please give me specific steps to know this in confidence from analyzing the blockchain. I just downloaded the full blockchain. I can obtain the data from glassnode, but I would like to check it for my self.

Thanks in advance.

I want to ask you that please tell me that how you do this. Downloading full block chain data is a difficult task and then check the whole data from this meta data. and then calculate the whales addresses. This whole process is a very lengthy task and also very difficult. If you calculate all the details so please tell the number of addresses and the date and time when you monitor.

Trades don't take place on the blockchain, instead majority of bitcoin trading takes place on centralized exchanges. So instead of blockchain analysis you should ask a centralized exchange to give you access to their database so that you can analyze what everyone is doing. Obviously they won't do that.

What you see some people do (like the scam site known as whalealert) is looking at the transactions and whenever it suites their trading goals they release it as a whale selling or buying bitcoin. Obviously no-one can know what that transaction was. Even if you can say for sure that it was from or to an exchange you still can't know if it was a buy/sell.

I am extremely skeptical of any statements by anyone saying that "whales did this" or "whales did that". It is impossible to accurately associate addresses with people or companies just by analyzing the blockchain. Even with heuristics and advanced surveillance techniques, I don't believe anyone can be as accurate as they want you to believe.

For Bitcoin (BTC)
You could try checking this thread created by the former forum member Lauda in the Beginners and Help section. I'd also advise you to check that board because there's many useful information for newbies there. From that list, any wallet will do, but the easiest to use is usually Electrum

For Ethereum or ERC20 tokens; MEW will do, you can check the above post from BitMaxz to see a guide on how to set it up.

Altough you said you didn't want to buy a hardware wallet, I'd suggest you do. They are not really expensive; and the security they provide is worth every penny.
Also, as a personal tip, I'd advise you to steer clear of any DeFi, ICO, IEO, whatever name the new HYPE scam trend has; because you will either loose time, money, or both

I would advise you to stop using bran wallets. Human-generated wallets tend to be rather easy to guess by other humans (and machines).

If you don't want to spend any money on a hardaware wallet, there are still plenty alternatives for both ethereum, any of it's tokens and bitcoin. Most of them are free and open source, and using them with some rather adequate opsec will save you a couple of scares if someone ever finds the word/s you've used to generate the brain wallet

I use 2.2 sat/byte fee, https://bitcoinfees.earn.com/ says it can finish in 15-300 minutes, but my transaction still stuck after about 10 hours.

How long it takes for the transaction to finish?

Thank you very much!

One hour or a couple of hours is almost impossible, the mempool has enough transactions over that fee to fill around 24 blocks, that's at least 4 hours if nobody makes any tx with a fee bigger than his during this interval.
I would say there is little chance to have that confirmed till Saturday morning.
