In the quest for market indicators, the $500 million worth of net inflows generated by Bitcoin ETFs last week cannot be ignored. These robust inflows punctuate the cryptocurrency narrative with profitable punctuation and hint towards a bullish future.

Summarily, the Bitcoin halving event looms large, casting shadows of opportunities and risks.
