An additional common mistake is searching for crashed coins, in accordance to their value against the Bitcoin, hoping they will return to their glory prices. So newsflash – there are coins which are light years away from their peak levels. Take Aurora for example; in March 2014 an all-time high price of 0.14 Bitcoin for one Aurora was recorded. As of the time of writing, Aurora trades at a 99.9% discount – 0.00014 Bitcoins. Could the (damned) Aurora make a move upwards 1000x? You’ll never know. You surely can’t assume a coin being lower than its peak price is an opportunity rather than a falling knife. There are also coins which disappeared and slowly got out of continuous trading – a scenario defiantly worth considering (especially with the low-cap and volume altcoins).
You don’t have to buy a whole coin. You can buy fractions of coins. Bitcoins are expensive currently in 2018, so consider buying fractions of a coin to start if you don’t have a big bankroll. It has historically been a mistake to buy only ETH and LTC because BTC costs more. You should consider which one is most likely to increase in and retain value. Buying all three in equal dollar amounts, and ignoring how many of each coin that amounts to, is one way to avoid making the wrong choice based on price tag per coin.
Payment Methods – What payment methods are available on the exchange? Credit & debit card? wire transfer? PayPal? If an exchange has limited payment options then it may not be convenient for you to use it. Remember that purchasing cryptocurrencies with a credit card will always require identity verification and come with a premium price as there is a higher risk of fraud and higher transaction and processing fees. Purchasing cryptocurrency via wire transfer will take significantly longer as it takes time for banks to process.
Don’t be greedy. No one ever lost money taking a profit. As a coin begins to grow, the greed inside us grows along with it. If a coin increases by 30%, why not consider taking profit? Even if goals are set to 40% or 50%, you should at least pull out some of the profit on the way up in case a coin doesn’t reach the goal. If you wait too long or try to get out at a higher point, you risk losing profit you already earned or even turning that profit into a loss. Get into the habit of taking profits and scouting for re-entry if you want to continue reaping potential profits.
