1. First one was 6th February. (BTC around $5800 and market cap around 280b)
2.Second one was around April first week. (BTC around $6500 andmarket cap around 255b)
3. Third one "now". I think this is another opportunity who missed last two. I think we can see the price around ($6800 to $7100, just my opinion)
Good news that, we are making lower high each of these stages. One day chart shows we do not have much momentum to deep much lower.
I'd say the entire 2018 up to now has been a good buying opportunity. A lot of times btc dived to good low points this year and many are just too busy whining about the bear market to see that we've been given opprtunities after opportunities to buy in and add up to our bitcoins.
