If you experience loses because of altcoins, don't be mad because it will happen due to your taking the risk of investment or else maybe because of your negligence. Because if you monitor your investment clearly and if you review the ability of altcoin you can choose it is impossible to happen.

Moreover, you just review and monitor your investment because if you can't do that you will not notice that your coin are possibly dissolved without knowing. Therefore are you sure that your altcoin site to invest is legit? nor I think the problems is site not the crypto altcoins, because I never heard any altcoins that vanished immediately into crypto industry.
