its better to hold the money and not invest it anywhere, investing gives you only low percentage profit and you have to risk loosing the money even if you think that investment is safe, the safest place for your money is your bitcoin wallet
Ok but whats the use of holding all coins in wallet, atleast by invest one can earn small amount of money... i dont say that invest all coins but investing small amount can be good
Having bitcoin alone is a gamble, since some actually believe it can just drop like crazy since its volatile.
Then again what Id ask, is whats not volatile since almost everything is.. but yeah just in general some people actually leave some out to lend on the exchange threads to earn more bitcoin which is what id consider if you have rep.
