I know it has been very dissappointed ride for btc holders for atleast 7 months but now the market has taken the much needed turn and all the fundamentals are also looking positive so expect bulls to survive for many weeks and to answer your question about previous high price level, my guess is that by the mid or end of september btc will break previous all time high level and grow rapidly.
Experienced investors now about the nature of bitcoin. They are holding bitcoin so patiently and not going to sell it. In fact they know the nature of bitcoin and they are now too much confident about bitcoin price that very soon it will reach to 20000$ very soon. Some investors are even confident about bitcoin price that it will reach to 20000$ before ending 2018.
