The past halvings ended in a sellout at first. Then after some weeks it started to rise and it ended about 18 months later in the blowofftop of dec '17.
I personally start to accumulate some BTC (and Eth & Hive) on a monthly base.

Corona and the just triggered world economic crisis are a wildcard though. :( A lot of ppl can't afford to buy cryptos during the crisis, unless we go as fast as possible back to normalty. It is what it is and nobody knows, where this all leads to.

So financial diversity is always a good thing despite all optimism for cryptos.
