Bitcoin doesn't seem like a gamble except for those who tends to make short term trade rather than going for a long term trade probably  after 2 circle. It's obvious the price of bitcoin fluctuates and that is enough reason for us to understand the risk and choose the investment strategy that best fits  our risk management plan. Shitcoins are the real definition of gamble coins how on earth can you explain the rugpull scheme on newly launched coins. Comparing bitcoin to those shitcoins the risk percentage is less when talking about bitcoin in term of investment.
