I have X Coin, I have a large amount of X Coin that I want to trade for Y Coin.
Problem #1: I'm afraid to use Coinigy & Shapeshift for such large amounts. (Shapeshift has limits and not sure how much I trust Coinigy since the rate you see can change; and no clear way to contact support if something goes wrong), they also don't have 'localbitcoins' for altcoins.
Problem #2: I'm afraid to use a normal exchange as it is such a LARGE amount and worried it will:
(1) Tank the market by 'dumping' on it -or-
(2) My account will get frozen, requiring more verification, and get reported to the taxman with IRS knocking on my door.
(3) That I'll lose all my gains during a hack or some sort.
I'm thinking the best way is to just stagger but let's say you have 100k, what amount would you stagger? How long does it take some people to close out their accounts of 'larger' amounts?
What are some other ways to get rid of altcoins you no longer want to reallocate your portfolio?
Just try to spend your amount into someparts if you are try to crashing the market through dump the coin and believe me there will your coin will be sold in the cheap price by the way like what was happened with ethereum in a half year ago.
