This is not aimed at you directly. Sorry if it seems that way.  Almost every reply ignores answering the question and defends crypto instead.

I can't begin to point out how no one is actually answering the question.  Instead of trying to defend crypto, why not just answer the darn question.  The question, has an answer regardless of what crypto does or doesn't do, or is or isn't.

Is there anyone reading this, who can provide some insight into ways of investing in crypto, or depositing money into crypto, that has the lowest fees. 10% to move money from bank, and back to bank seems extraordinarily high.  There must be a better way.  As a test, I put $300 in a couple of days ago.  I'm going to put it all in my bank, and see what the round trip costs me.  Then I'll know a real world example. 

Then I'll put that and more into several different crypto currencies.  I just want to come up to speed quickly, so I don't put it into an exchange or network that's going to wipe out any gains.  Let me put this another way, say you had $10,000 extra, what system or network would you use, that has the lowest fees for depositing, transferring, and cashing out?
