Hmmmm,
Only a little while ago Bitcoin was somewhere around $12K-13K, now it's sitting around $9k. Do you think it's a good idea to invest cash in Bitcoin at this time hoping that in six months to a year or two it'll raise up again ?
Ain't got a clue. Anyone who claims they do have a clue is a bit of a twat. In general though there's no sign of Bitcoin's spread running out of steam. If you sit there long enough then the chances are good things will happen eventually.
