Yes, you can easily invest as little as 100 Indian Rupees (INR) in Bitcoin through various cryptocurrency exchanges and digital asset trading applications operating within India. Because Bitcoin is infinitely divisible down to satoshis (the smallest unit of Bitcoin, where one bitcoin equals 100 million satoshis), retail investors do not need to purchase a whole single coin. Platforms allow fractional purchases, meaning a 100 INR contribution simply buys you the corresponding fractional decimal share of a single Bitcoin based on real-time market conversion rates.
