What we've done with this analysis is we have computed the average weekly returns spanning between 2014 and 2020 for BTC, ETH, Total Market Cap index and Alts Market Cap index. We then analysed this data to project which weeks are likely to deliver the most returns given that Q2 is highly bullish. We've created this analysis as we are using it ourselves to pinpoint when we want to start trimming positions and fully rotate out of sh*tcoins (i.e. sell them in full) to avoid bag-holding.
Before you proceed, please note that this data is based on averages and just because it happened in the past, it does not mean it will play out again. With that being said, we personally believe what Mark Twain once stated:
"History doesn't repeat itself but it often rhymes"As this section is just a summary, we've taken all the data and plotted the "Cumulative Returns" delivered by each of these assets/indexes.
No matter how much data one gathers, it is impossible to determine exactly when the top will form but we can get pretty close to it and that is what we aim to achieve here.

The general consensus is that the second quarter (Q2) which spans from April till end of June is a bullish period for BTC. The most bullish month out of them being May. On the other hand, Q3 is not as bullish and tends to be choppy (stagnation) or bearish. Given the fact that we've seen a very sharp rise in price, the most probable outcome is a Q3 correction between August and September.
Now that we've pin-pointed which months have been the most bullish/bearish, let's zoom in a bit further to see which weeks in particular were responsible for the majority of the returns:

Overall it's obvious that the majority of returns statistically happen before mid-June. It is factually correct that Bitcoin's price does grind up after mid-June slightly but the market strength starts dissipating. We have seen larger than usual returns this year and hence when the strength dissipating it is more likely that the market corrects.
Today is May 9th, the week ahead has historically brought an average of +4.60% for Bitcoin's price. The larger returns spanned between May 23rd till June 12th.

The same conclusion of Bullish Q2 can be stated here for ETH as well, with May being more bullish for price than April - which at this point may have become obvious with ETH approaching $4,000. Q3 is where ETH weakens on average and hence planning accordingly may be beneficial.
Now let's zoom-in using the weekly returns:

The same observations from BTC can be applied here but let's look at individual weeks (today is May 9th) - we're looking at the most interesting ones only:
End of May till mid-June will likely be bullish after which price action has historically weakened.

The similarities are very strong, with April/May being very bullish, followed by a weaker June, a rebound in July and weakness showing up again in the market in August and intensifying in September. Now let's zoom in:

If we were to breakdown this data it would be as simple as: April is bullish, May even more so while June is generally weak with a rebound in July before more weakness. Of course this is an average and not a 100% predictive model.
