BERLIN, El Salvador (AP) — At a geothermal power plant near El Salvador’s Tecapa volcano, 300 computers whir inside a trailer as they make complex mathematical calculations day and night verifying transactions for the cryptocurrency bitcoin.
Crypto exchanges on a growth path shared a few common traits: they're larger, more innovative and offer more digital assets than their competitors.

Plenty of altcoins have also taken a beating. Dogecoin erased the breakneck gains of the week and then some, nearly halving its price after a meteoric climb last weekend. XRP is down 35% week-over-week, Stellar is down 30% and Polkadot is down 25% since last week.
We also consider two additional factors that account for the finding that in some periods prices drift away from fundamentals. The first factor is the return of Bitcoin. We argue that Bitcoin, being the largest and most traded cryptocurrency, is the most perceptible to sentiment and speculative trading by investors. Thus, as a factor, it can capture periods when trading forces unrelated to fundamentals are the strongest. The second factor is a cryptocurrency price momentum factor that we construct following the seminal work of Jegadeesh and Titman (1993). Momentum effects have been linked to investor psychology (e.g. Barberis et al. 1998).
