For me, Bitcoin is the best choice for long-term investment, this is very worthy and valuable for the future. I believe by investing in Bitcoin, we can earn much profit if we are able to be patient by waiting for the bullish. It means that we can use the cycle of bearish and bullish to buy and sell the coins. So we can maximize the chance to get or earn profits.
But if we are talking about trading, I will prefer to try altcoins that have low prices. Because I don't have much money so the best choice for me to earn higher profits is by trading altcoins that have lower money. So far, this is very risky but this is the best thing to get for me if doing trading with risks.
trading on altcoins, moreover new altcoins are more risky, because their movements are difficult to predict. this is different from bitcoin which has the highest market capitalization, so it is still possible to carry out chartist technical analysis using various approaches. therefore in my opinion the best place to trade is in bitcoin, especially if it is for the short term. but it will indeed be easier to invest by buying at a low price and selling it according to the profit that has been targeted
