I bought BTC and LTC in 2013. I had to sell BTC, because I needed the money. But it was way too early
LTC was back then 4 USD. I think it broke 40 USD in the same year, then it got back to 4 USD again. In the last months LTC broke 20, Nigeria might have played a role. A lot of people started using the coin as currency. Now it broke 40 again, probably because Charley Lee left Coinbase and joined LTC fulltime. LTC I still hold and treasure.
I kind of missed ETH, I was too late. So this year I invested in Golem, after listening to some interesting podcasts on Epicenter. In April I bought Golem for 0,10, now it’s at 0,50. It won’t be so big as BTC or ETH, because the scope of the application is smaller. Nevertheless I think - or better say hope- it has plenty of room for growth
I bought Golem via Poloniex and Liqui.
I only invest money what I can miss.
