Actually for me btc is always the best currency which I like for holding, trading everything. But I never want to manipulate the market because I don't want to run with small funds. But when the market is bearish then I rush to buy. Since I am a small trader so any profit of big or small, gives me comfort. Also, if you want you can buy some of the best altcoins without high risk such as like eth, bnb, sol, ton. I think you should always lean towards top currencies because you can get good profits from such currencies in a very short period of time.
