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.
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.
