The other major risk to be aware of is that hackers are always looking for vulnerabilities to exploit. One example is the more than $30 million worth of Tether coins that were stolen. The most surefire way to ensure the safety of your coins is by using a hardware wallet such as these by Ledger. Keep in mind that this will slow down your ability to trade those coins, as you will be transferring them between the device and your exchange accounts (more on wallets and exchanges soon).
From a trader’s perspective Smith also discussed key BTC prices, namely the $5,800 support level and the $6,800 resistance level, noting that the recent lows of bitcoin are practically the same ones that were touched in April and February, earlier this year. Curiously, these were the same points BTC was trading at last October when bitcoin futures were announced and the price of the world’s most popular virtual currency skyrocketed.
At this point, you have narrowed down your list to a few cryptos that have a good potential for profitability. But you need to narrow down further and find the ones that have the potential to take-off faster than the rest. That’s why you need to keep in touch with the news.  Check out crypto news from different sources to determine, which of the cryptos you have in your bucket-list have some interesting news coming up.
Use small buy-ins, and don’t margin trade or short unless you know your stuff. The smaller your bet is compared to your total investable funds, the less risk you are taking on every bet (one of many insanely important things we are covering here). Putting it all on black is tempting, but then if it comes up red, you have nothing left to invest. Live to fight another day by learning to manage your buy-in size. As a rule of thumb invest 1% or less per buy-in (yes, that small, really; losing 100% of 1% leaves you with 99%, losing 1% of 100% leaves you with 99%. Small bids offer the same bet, but with way less risk). Put reward aside and practice risk management and capital preservation until you are very experienced (and thus, by logical extension: don’t margin trade or short unless you know what you are doing, as those leveraged bets magnify your risk by their very nature). See Kelly criterion.

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.
