If I were you I would just let my bitcoin stay's as bitcoin we are in a bear movement and I think you would gain more if you would let it stay safe in the bitcoin room and let Altcoin perish in the dark, Because we don't afford for bitcoin to go down anymore and you will be one of the people that sold their bitcoin to make it go down any further, Well that is just my suggestion and if you truly want to invest in some projects because this is your money then use fiat money in buying Altcoins and for me the Altcoin that I think that will last and make it big in the next bull run will be,
1 Ethereum
2 Presearch
3 Binance
4 XRP
5 Monero

Just a limited that I can think of but I didn't put the rest of my portfolio I just choose of the top 5 that I think, And even though I share this to you I still consider your decision and I am not a financial advisor and this is just speculation or a suggestion.
