There is something people does not understand for investment and the trading someone who is a trader of cryptocurrency that person is not an investor but someone who purchase different kinds of cryptocurrency and hold for long time or a short time that person can be classified as an investor not someone who is a trader, but people in their own way of understanding things they do say that a trader is an investor I think it is a misconception from my way of understanding what is threading and what is investment, who purchase a Bitcoin and the sell within a short time that person will be probably called an investor and is equal as someone who purchase a bitcoin and the hold for long time.
Your explanation about Bitcoin investment seems to be inaccurate because there's no short term holding or short term investment in bitcoin. Investing in Bitcoin require one to accumulate and hold for longer period of time for it to yield good profit over time. Then in regards to purchasing different cryptocurrencies can also be tagged as gambling because shitcoins and Altcoins lacks growth fundamentals, its important to focus and channel your funds on bitcoin which has shown resilience and profitability over the years, can be more vital move compared to investing in cryptocurrencies that might lack solid growth fundamentals.
