I use coinpot.co with 5 micro wallet btc,bch,ltc,dash,doge and i can earn with their faucets while i use it then i use this because i don't have fee in this everytime i transact some btc to our country wallet even so risky and they already have scam accusation but i use this for so long and i never experience or got scam in their micro wallet actually some post here will recommend you hardwallet and blockchain but i think if the btc are small only like 0.07 btc then if they scam that it's really low and i can afford that to lose,In ethereum i like myetherwallet then trading site that i recommend are binance and mercatox

I use also hardwallet and different kinds of wallet before but for me that only have a little btc only i think better for me to use micro wallet only and i save some btc in our country wallet(coins.ph)
