I wanted to write this review because of another review above that claims NANO (formerly Raiblocks) was hacked. NANO was not hacked. Bitgrail, one of the exchanges NANO was on had an issue with their node that the exchange to be hacked. They tried to hide it and 17 million NANO were stolen. Kucoin faced the same issue but immediately caught it and worked with the devs to fix it and faced zero issues. This was entirely an exchange issue, and not a problem with the NANO block lattice.
