If the OP is still afraid after fully understanding crypto and bitcoin investments then leaving investment in the crypto sector is quite acceptable. because if the feeling of fear dominates too much then it is feared that when the OP has bought at the current price and it turns out that the price has decreased slightly then because the OP has excessive fear it will make him panic and sell in a loss position. so I think OP really should be able to control these feelings of fear. because fear and greed are always used as certain indicators in crypto trading and it can hurt us if we can't control it. because high volatility will always exist in bitcoin and altcoins.
It will take a lot of courage to start investing in crypto or Bitcoin if we don't have too much extra money to invest with or we only budgeted our salary to make a living, it will be better first to start finding extra Job that can help to fund first the investment before entering in Bitcoin or doing trading. It's too risky to invest only our few money without backup if we know where not that capable yet of understanding how Bitcoin or trading works. Once we have extra budget for it the burden or fear will be lessen knowing that money is allotted for investment.
