First, this is very important. You have to research before you buy anything. For instance, any coins that you are planning on buying; find and read their newsfeeds. Additionally, you can search the web as well. For example in Coinbase, there are charts for your reference so you can decide when to buy in. My best advice is buy that particular coin when the price is currently low, the reason behind it is no brainer - you need to buy at low price so you can save money.
You must check, and study every website , if possible, for that specific coin you are buying so you can learn what they are trying to accomplish. The best place to learn these things are in groups or communities.
Moreover, my experience is that, you should focus on the top 25 coins in the market today. Please familiarize with these websites where you can learn about the latest of each cryptocurrency you are looking at.
The following websites are best in my opinion:
cryptonews.com
coinmarketcap.com
markets.businessinsider.com
Financefinance.yahoo.com
coindesk.com
In my experience I stick to the top 25 coins because it gives you the best results. For example, I have $1,000 I would put $200 for the first top five, namely:
Bitcoin (BTC)
Ethereum (ETH)
Binance Coin (BNB)
Cardano (ADA)
Polkadot (DOT)
Coinmarketcap.com
And by the way, if you encountered stablecoins - stablecoins are similar to the fiat dollar in value where it is fixed as 1 is to 1.
You will not be investing in those coins.
Also, more coins that have the potential to go higher in the next few months are Chainlink (LINK), Stellar (XLM), Tron (TRX). And especially XRP Ripple this cryptocurrency is at the top for a while now so there is opportunity for the said coin.
If you are into swing trading I can say you can take advantage of it by profiting. Swing trading works when you buy a particular coin and then you hold for certain period of days or sometimes weeks and then sell it in order to profit. Rinse and repeat the process.
You know, one of attitude everyone should possess in trading with these coins is Patience - do not be emotional or get depressed. It's just how the market works. You win some, you lose some.
Cheers!
