I bought BTC and ETH in december, those are up over 100% now. Let's see how long that lasts. Also got a bit of GRT and XLM. BTC and ETH just to jump on the train, to see if the expectations of value rise due to diminishing supply and institutional investors getting involved pan out. Definitely would not put any savings there and am prepared to lose everything any day. GRT and XLM are something completely different, GRT is basically a supporting protocol for ETH, allowing indexing and queries. I have no clue what practical benefits that could bring, but they just announced they're trying to expand to other coins so stonks. XLM's main purpose is to allow easier, faster and cheaper financial transactions between different currencies and cryptos, it may actually have some real world use, maybe?

I'm no finance professional yadda yadda and none of this is investment advice nor do I at all know what I'm talking about.
