I never mean to say that don't invest or you might get to 0, but currently, we are experiencing high volatility rides and you never know what are the floor/peak levels...
I would still stay away from BTC investment currently unless it comes back to $270, that's a nice buy floor for me right now...
$300 also a nice price for invest in BTC price, at least in future more people will use BTC as their online payment. And that's mean BTC value will keep grow a bit from $270.
In my opinion, $270 is quite hard. But no one know about it.
With the current trend look like that $270 will only occur if there's somehow a major changes to affect the price like when XT drama happen.
$300-$320-$350 I think is the right price to buy btc's for today. I see that price has strong support today for $360 above so I will guess that no $200 mark will happen for a months.
