About ATH: breaking it in one year and a half seems too optimist to me. I won't be surprised if the next bubble doesn't happen for 2/3 more years.
...and the ATH was broken in less than 4 months

Anyway, what is clear from this thread is how
hopelessly wrong people are when trying to time the market (not talking about you specifically Rampion). It doesn't matter if you lived through 2011 and April 2013 bubbles and you think you know the markets inside out. You might get lucky and catch a falling knife (or call the top) successfully, but that's just gambling.
I do think that 2011 won't happen again. Things changed, people knows BTC is here to stay for good while in 2011 Bitcoin could have very well disappeared. The sentiment and the level of awareness are completely different than in 2013.
