[assuming you really want to sell $100K worth of bitcoin]
a word of warning:
you may encounter some problems with your bank because that is a large amount of money and it is clearly going to come from a bitcoin exchange service and depending on your country, your bank may flag your account and you may face some troubles this can be taxes or worse.
I did not think about that... thanks. I have to find out if whatever I sell in Coinbase automatically gets transferred to my bank account... or if the fiat stays in Coinbase until I choose to withdraw. I'm sure I will be flagged at one point... but who knows, maybe in 2-3 yrs I'll have less reasons to use fiat
Are you planning on leaving the cash on the exchange while you wait for the price to drop?
Otherwise you will get into issues with the banks and tax agencies when you get a big incoming transfer (>10k in most countries), which will be investigated. If you didn't pay tax for instance, this may cause problems if you can't explain where and when you got this amount from.
If you plan to trade it within days, you may as well leave it on the exchange, as transfer times between banks will also take days before your funds are withdrawn or deposited.
Yes, ideally I'd like to leave the fiat in an exchange. Do you know if Coinbase holds the fiat after I sell BTC? Or will they immediately withdraw the fiat to my bank account? I would rather withdraw the fiat to my bank acct in small segments... I can imagine how much of a red flag they'll have if I suddenly deposit a large sum of money
you can sell your bitcoin in any how amount in localbitcoins with safe because a lot of people using the localbitcoins for buy and sell bitcoin and i often sell my bitcoin in to localbitcoins without any worry.
I'm not sure I feel comfortable with localbitcoins, but i'll give it a go. Thanks
It's absolutely crazy to store amounts that large on Coinbase or any other exchange if you ask me. The risk of hacking or arbitrary account freezing is far too high. I seriously doubt that the possible return of trading activity you seem to have in mind is worth this risk. And even if your trading ideas could be implemented, there's no guarantee that you will generate a positive return of investment.
However I doubt they can be implemented. Even if you manage to get past the highly privacy invasive registration process of an exchange (like Kraken) that allows you trading huge amounts and you succeed in convincing the governmental bootlickers at your bank that you're not a money launderer, you will discover that the exchanges are not offering sufficient liquidity to make trades that large profitable. The slippage is enormous.
You will have a less stressful life if you just start slowly withdrawing your funds from Coinbase to addresses you control. Bitcoin's purchasing power will appreciate more than enough to make you a happy man by simply hodling.
ya.ya.yo!
This will sound stupid coming from a poster with a "legendary" sticker, but the reason I keep all my BTC in Coinbase is because I'm afraid of losing the BTC if I mess something up on a private wallet. Exchanges get hacked all the time but Coinbase has taken much greater measures to maintain a level of security over an exchange like BFX for example. I heard they keep 98% of their BTC in cold storage. I feel a little bit safer keeping it there than trying to keep up with a paper wallet or trezor
