I prefer a long term investment, so I will hold the altcoin I believe most in sufficient time, in order to earn more profits
I am a Hodler too but only with a Billion coin supply Altcoins like Ripple, Dogecoin, Verge, Stellar, Tron, Cardano etc.
I am holding each of these coins worth $1,000 when I bought them all last early last January this year because that was a mega sale and almost everything are on their lowest values.
I never regret when I bought those coins last month.
So, aside of Holding the coins mentioned above, I also tried to trade using USDT as my stash money. USDT Tether is the most important Crypto in the market for me because it will be never affected when the Crypto Doped or pump. You can always reserve your stash coins though USDT.
