That's a good idea to start anyway.  And I would advise this gentleman not to buy crypto on margin if he doesn't know what he's doing.  Leverage works great when you're on a roll, but it can wipe you out faster than you can blink when things go south.  And as to whether bitcoin is too high...that's the thing.  If you wait for bitcoin to come down to a certain price, what if it doesn't?  What if we're on the way to $3000 as I write this?  That's the question that every trader has to answer for himself, and there isn't anyone on this forum who can tell you with any certainty where the price is going to be by the end of the evening, much less a month or a year.  You got to make that call yourself.
