Keep calm, this is still a big load of money.
Since you are this young , you may encounter some problems with cashing out large sums. ( At least this is what it would be like here in germany.)
Your Bank would probably tell your parents and you may not have control anymore over this money.
So you have to be smart about it , and while its painful to see it dropping wait a bit.
Cashout a small amount that you feel comfortable with having on your bank account via bitstamp.
Like others pointed out , use localbitcoins for some additional cash.
I will not advise you on any altcoins because you probably can loose a lot of the money there.
Hold the rest until you have an age where control of this money is guaranteed yours.
I think your right it would be the same here in UK. But it ok I will help my parents out there old and cant work. But it is a smart idea no lie. But I am trying to verifying with local bitcoins but when you have the money dropped in your account. Is not taxed and could this be a volition of the FSMA 2006 namely money laundry regardless of the sale being done in good faith and clean hands (lord diplock).
The most F****D up thing would be if bank seize the money under money laundry under the this act the bank cant tell me anything (breach of tipping off). So I will be screwed big time. They may even use the Precedes of crime act and seize goods that have that could be obtained from my profits. What do you think?
Why do you think alt coin wont increase in value?
