If you choose to keep some stored on an exchange or a website such as Coinbase, then ensure you complete a full security setup and ALWAYS setup Two Factor Authentication, I recommend using Google Authenticator for this and not SMS Two Factor Authentication as your phone can be compromised by hackers. Google Authenticator creates a random number string each time you log in to protect yourself in case someone can get hold of your username and password.
All of the different techniques used to track the price of Bitcoin and other currencies have one common factor- they require investors to remain up to date on the latest market movements. In addition to keeping track of the cryptocurrency market, it’s also necessary to buy and sell on an exchange, select a Bitcoin wallet, and make analytical interpretations of the statistical data gathered during market observation.

Verification criterion- Since cryptocurrencies aren’t government regulated, trading on exchanges is posed to hacks and misuse of identities. Therefore, all the reliable exchanges will ask you for the verification of your personal identity in one or the other forms to make deposits and withdrawals. To remain on the safer side and avoid money laundering and frauds, you must opt for the step of identity verification while registering on an exchange.
Maybe you remember when, thanks to The Wall Street Journal, everyone thought the SEC was going to meet on May 7th to decide whether or not Ethereum (ETH) was a security. If you had taken up a large position in ETH prior to the 7th, you would have been disappointed when the price fell from ~$793 USD to ~$743 USD amidst news that there actually was no meeting after all.
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.
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
