What does "24h Withdrawal Limit:" "In Use:" mean in Binance?

I have a
24h Withdrawal Limit：100BTC In Use：0BTC

Does this mean I can only withdraw 100 BTC? How do I raise the limit?

Please help me understand.  Thanks.

Hi folks,

I'm new to crypto as well as wallets.  I recently purchased the Ledger Nano and moved some coins on it.
However, I made an attempt to withdraw all of it to an exchange, but when I did, it didn't move all of it.
I understand I'm charged fees which is fine, but is there any limit of withdrawal or restrictions?

Thank you in advance.

How do you install this app on a Mac using Google Chrome browser?  It just says "Launch App"

Is there a way to launch the Coin's app without always having to go to the Ledger Nano website and clicking on Apps link?  What happens if that website gets hacked?

Are there any fees for transferring cryptos to hard wallets?

That didn't work.  I am still locked out.  I emailed support, but I emailed them before with no response.  Is hashflare a fraud?! 

I just signed up for Hashflare and I am getting an Error 1015.  What is this?  Why am I getting it?  I'm not running any bots and I rarely trade much

I thought signing up for Bittrex I can exchange USD to Bitcoin Cash, but instead it requires USDT.

Anyone know of an Exchange for USD to Bitcoin Cash and viceversa ?

I am trying to transfer .001 ETH from MyEtherWallet.com to an exchange, and while I realize I may not have enough to transfer, it mentions I need "GAS".

I tried reading and understanding the process, but it is still confusing.

I get the Error Message: Transaction gas is too low. There is not enough gas to cover minimal cost of the transaction (minimal: 21000, got:1). Try increasing supplied gas.


I type 21000, but I still get an error message.

How do I get to understanding GAS

Do cold wallets have to use GAS?  ie) Trezor/Nano?
