Don’t go downloading random wallets or clicking on random links, but do accept that you have to share information with exchanges. There is some malware out there, and you need to do research and be careful. However, for all you want to protect your privacy, you have to share your info with exchanges you want to use. So share what you have to and download apps as needed, but be careful and do research.
The motivation for the investors is that the token will be traded from day one on the exchanges and would yield a nice profit to the ICO participants. In recent years, there have been many successful ICOs, both the project itself and especially in measuring the yield for investors. Coins doubled, or tripled, their value and much more in relation to their value on the crowd sale. Augur’s preliminary crowd-sale (we reported on it previously here) yielded investors a phenomenal 1,000% for their investment. Okay, but what’s the catch here? Not all the projects benefit their investors. Many ICOs proved to be complete scams, not only were they not being traded at all but some projects disappeared with the money and we have not heard from them right up to this day.
Accept that coins can go to zero, and even good coins can lose up to 80% of their value (especially against BTC). There are many coins that didn’t make it to 2018 that were once highly valued and popular. Meanwhile, even some giants of today like ETH and XRP have seen their value in BTC prices drop to depressing levels. You should prepare for this mentally and have a strategy that factors this in. If you buy the dip in ETH from .15 down, .08 may look like an excellent price, but you have to be ready for .02. ETH holders who didn’t prepare for this had a depressing June 2017 – December 2017. Heed my warning, that new coin doesn’t have to moon twice, it can go to literal zero, and even those that will moon again… they can have long seasons of stagnation in between (where they lose value against BTC for months on end). See the Crypto Graveyard and please look at the historic charts of major alts like XRP (the gap between moons is real and some coins really don’t make it).
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.
