NEO is a centralized coin cause some of it nodes were controlled by some organization.
DOGE was not doing well in the market ever since the 2016 but gain some pump which might be through market manipulation.
Be more careful buddy.
I believe that new coins have more prospects for multiple growth in price and therefore prefer to invest in new coins
Yes, some new coins has the potentials and utilities to survive the crypto currencies market but you do your research well and choose wisely before putting your money because there are still some fake new coins out there.
