Mexico’s third-richest billionaire, Ricardo Salinas Pliego, gave some advice Saturday about investing in Bitcoin.

Salinas is the founder and chairman of Grupo Salinas, a group of companies with interests in telecommunications, media, financial services, and retail stores. According to Forbes’ list of billionaires, his net worth is currently more than $13 billion.

The billionaire tweeted Saturday urging his Twitter followers to buy Bitcoin and keep buying while the price of BTC is still low. His tweet reads:

"You have to buy bitcoin (keep buying when the price is low), then just hold your BTC, forget about selling … Trust me you’re going to thank me later."
