My method of buying is when the price is low so that I can maximize the money that I will put into it, I think that it has been my mantra ever since my friend introduced me to bitcoin.
If you will strictly follow that, I guarantee that you'll be able to grow your money here in crypto, but make sure you don't buy shitcoins, and to be safe, just buy bitcoin and just do that strategy every time you see a great entry price and then sell when the market is bullish again.
with the bitcoin's volatility, you can expect your money will grow in no time.
That is one of the basics of trading, to.buy low and sell high, that is what gives profit. However, it's not always easy to edtimate how low the price will go and when is the best time for buying. The same refers for selling too. So, there is always certain amount of risk and possibility for bad judgment, otherwise trading would be very easy, wouldn't it?
However, I completely agree that the best option is to stick to Bitcoin, experimenting with bunch of anonimous coins is not the best strategy.
