That's why OP speaks about lottery ticket - if you buy lottery ticket you have no certainty you will won anything

But if you have some luck you can end with decent profit:

Interresting stats. NXT is very interresting. I heard that whole ico was set on BTT in a topic that looked like :
I've created new coin. Send me some btc tips and i'll send you some of my coins. That way he raised 16 k $ and send 1 bil tokens for that. That's how big risk some took to get that big reward.
Edit:I've found it:
At the present moment development of the software is not completed. While Im working on it we should start the transfer process to decide who and how much coins will get. This will be done by sending a
small amount of BTC to my own address. I bet most of you have just thought I got the catch!
Hold on, I dont ask you to send thousand USD worth coins, a few satoshis is enough. A special message must be attached to the transaction. This should be done via
blockchain.info which supports such the feature. The message must contain only SHA256 hash, that will be used to claim coins. All these coins will be put into the genesis block that Ill publish before the launch. Anyone will be able to make sure that the 0th block contains only legit coins and there is no premine.
So, if you want to get coins do the following:
1. Choose a secret phrase
2. Calculate SHA256 hash of this phrase (an
online calculator can be used)
3. Calculate SHA256 hash of the hash you got on the previous step
4.
Send any amount to 1BCN1ugdKdWd9pQ8Am9hMhtHZfmbXzxE8a, dont forget to attach a message with the hash you got on the 3rd step.
(The amount is capped at 1 BTC!)Thats it.
When Nxt is launched you will get part of new coins and your stake will be proportional to the amount you sent. So in my opinion it was a testing rather than ICO. Its crazy how price rised. He was asking for any amount but not more than 1 btc (130 $ than in 2013)
