i really need a trade limit of more than $10,000 on coinbase exchange..... $10,000 daily buy limit is plenty for me... i am planning for the future just in case. i am all cash on coinbase exchange.. and the only way i get more money into the system is to buy more bitcoins through coinbase....or circle. however, circle's $300 limit every seven days is ridiculous.
If you really have that much money (more than $10k per day) that you anticipate that you may want to inject into the bitcoin ecosystem on a daily basis, you can send money to various exchanges... Gemini, Bitstamp, Uphold. Some of them allow free ACH transfers such as Gemini and Uphold, at least for the moment. Uphold has a $3,000 weekly limit, and I am pretty sure that Gemini has a lot higher limits, maybe even $10k-ish per day? I cannot find that information at the moment.
I have done the Uphold and Gemini ACH deposits (but I just logged into my Gemini account, and it appears that I am no longer able to make a direct ACH deposit without first providing them with additional identity verification - which seems to be an increase in their verification level). Actually, with Gemini, I think that they are doing fine and increasing some of their offerings within US regulatory (and consumer protection) requirements, but I became a little disgruntled with them, when a few months ago, I was negatively affected by their reversal of a fat thumb transaction and I complained to no avail (and thereafter removed most of my funds from their exchange). Anyhow, I think that there are some other fairly safe exchanges that may allow the same kinds of ACH transfers that are either free or nearly free (but I have not checked them all out).
Anyhow, once you have set up other potential free avenues for transferring your money, then you can continue to send dollars to each of them (and maybe even max them out) and wait to buy the BTC.. or you could either buy BTC right away and transfer the BTC to another location and convert back to dollars, or leave the purchased amount of BTC (or the dollars) in the location that you bought/transferred them.
Especially compared with about 1 or 2 years ago, there seem to be a lot more options of various services to spread out your money and to be able to get passed some limits (although your bank may begin to question your activity, unless you have more than one bank account, which could be another option) to send in a lot of money, especially if you establish multiple accounts, rather than seeming to get all worked up about Circle's low initial limits. Circle is a lot more tailored and designed for smaller personal uses, which you seem to require more and causes their $3,000 per week (once you wait out the initiation period) to be sufficiently large for a large number of "normal" people (mostly located in the USA from my understanding, but they are working on a larger global presence).
We all probably already realize that if you, Mr. Aztec, are not trolling us, you are probably also not very "normal."
Look at me, look at me, attempting to help out the Mr. Aztec, even though he frequently acts like a little turd.
