the most important indicators are hype and fomo, so you can invest in hype altcoin to get profit, but of course you shouldn't be greedy and have to sell it immediately if you get profit (my advice is 10-20%), but if you want to invest safely without paying attention to indicators, then you better invest in Bitcoin, because when market conditions are good, then of course the price of Bitcoin will definitely increase the first, so you will definitely get profits from investing in Bitcoin quickly.
