Funny thing is most of the coins recommended here in the comments seem to have pretty much the same chart - gone nuts this week - which usually means they will drop back down to trend line over the next month.

On these four you could get lucky, and we do have a small amount of Dogecoin, but overall these are just too speculative for me to get my head around.

I guess I'd rather miss out on the chance of huge initial gains and mainly go with investments I can assess more like shares which is what I used to trade in.
