The best thing one can do in my opinion is to DCA bitcoin indefinitely through bear and bull markets. Price goes up, price goes down.  It always does.  But just continue to put in/accumulate, and you'll have something of value that no one can take from you.  It is such a rewarding experience to hold an asset with the ability to transact for yourself.  The longer you hodl, the more you realize it isn't about price.
