I guess you meant "alts". For a sec I thought I saw atlas there and that would've given your post a whole different meaning. Well, the important thing you've to know now is that the alts season is yet to kick in. Bitcoin is still in full dominance of the market. Just ignore the flashes you see in price rise of certain alts. The real alts season starts when Bitcoin is exhausted. At the moment, Bitcoin isn't relenting yet. Talking about exit strategy, I think it depends on your risk appetite. Some investors will just aim for X10 as ROI and then sell off while others will want x3, or x100. It depends. But my advice to you — whatever you do, don't sell off yet. We are in a bull season.
