Bitcoin have remained a reliable way of saving money, inflation resistant and constant growth over the years. The risk is minimal and the reward unimaginable. Always keep this saying at heart, "if the potential reward of doing a thing is greater than the risk, do it anyway"
Bitcoin has become the greatest coin in the world for saving money and earning more profits, which is why many people prefer to have a Bitcoin as an asset rather than investing in any other currency, which can result in them losing their entire investment. Because, all this while the market of altcoins is not encouraging. However, they just follow the Bitcoin market; but if it falls, they will also collapse. When the Bitcoin market begins to grow, instead of altcoins should follow up, but they will not.
That’s why since their market has been reduced value and there are no signs that they will soon return to their previous level of value, not everyone is as interested in investing in altcoins. Additionally, because Bitcoin is a reliable coin, many people decide to hold it as an asset because of its high market value and quickly growing rapidly.
