Robert Kiyosaki, the best-selling author of 'Rich Dad Poor Dad', has predicted that Bitcoin (BTC) could reach $350,000 in 2023. Kiyosaki made the prediction in a series of tweets, where he also stated that the collapse of FTX has given whales an opportunity to accumulate more BTC under $100,000. "The implosion of the world's largest asset manager and issuer of the Bitcoin spot ETF, BlackRock, has given the whales an opportunity to accumulate more BTC under $100K," Kiyosaki wrote. Kiyosaki added that he prefers to hold physical Bitcoin in his own wallet and does not trust the Bitcoin spot ETF held by BlackRock. "I will continue to buy because BTC is going much higher," he wrote. "I prefer physical Bitcoin in my own wallet and do not trust the Bitcoin spot ETF held by BlackRock." Kiyosaki previously disclosed that he owned about 73 BTC in November and aimed to increase his holdings to 100 BTC in a year. ```
