I think we must always get some altcoin that solely has smart in essentially and get them with paired with USDT if you'd wish to hold it for long term, however, if you purchase altcoin with BTC ought to be done the short trade as a result of the worth of BTC growing quick currently. In my opinion, smart altcoin in basic is ETH,WAVES,XMR and DASH. ETH is incredibly smart altcoin as a result of the worth on was ICO is regarding $0.3 however currently around $350.

It is wholly up to you, however, i feel it might be higher if you'll be able to gain your altcoins from free sources like delivery or maybe do some activities to induce bounties that means you are doing not got to invest within the initial place. However, if you urgently need to speculate in it, you'll be able to concentrate to the various devs of the altcoins, if the devs square measure serious and making an attempt their best like listing it on exchanges, etc. then you'll be able to actually invest in it.
