LEO is traded very recently between 0.15 to 1.5 Steem. I have just picked a justified random number of 0.25 Steem (https://steem-engine.com/?p=market&t=LEO). Rest of the numbers is just for examples. BTC can reach $250K, Steem can reach $50 or LEO can be $1, who knows.
For my personal reference, I have bought BTC at $75, LTC at $1.5 and off course Steem as high as $2 and low as 16 cents. I have to yet make any profit from my investment since I lost all my earlier coins in daytrading and future trading. However, never a mistake, always a lesson. May be this time, I am prepared enough!
