It's really hard to make a profit in times like this where the market doesn't move much, especially if you're spot-based. Although if you base your profit on futures trading, the price of bitcoin is not that volatile. But you should always have an understanding of futures trading.
And if you ever do the futures trade, don't ever try to trade in other crypto's; instead, just focus on BTCUSDT so that you are at least safe, but on the spot instead of trading, hold and DCA, that's my advice.
To get the best results from the spot, of course it takes quite a long time so that the results can be maximized. What do you mean never try another trade with just Bitcoin and at least be safe? As we know, futures trading certainly has huge risks, both for beginners and experts, there is no safe word there. And you need to remember that there is no investment whose value is not too volatile or stable for that matter.
