Did you know that there are 2 special whales that go by the name Mr500 and Mr100. Both bitcoin whales bought respectively 500 and 100 Bitcoin every single day for years. The strategy they use is called "$ Cost Average" and consists in buying at exact intervals that can be each day/week/month the same amount. This allows to capture the upward trend and passively invest into something. This is mostly used in stock trading investing in ETF that tend to always go up over time. This is done by rich people that want to protect their wealth from inflation. The question is, when those whales will decide to sell and when this will happen it will be the worst day for Bitcoin in history.
